Over the past decade we seen at least $1 trillion dollars spent by private equity firms. These firms have taken over companies for a pittance and then pillaged them by slashing employees and cutting costs. They then used the money to pay down debt rather than rebuilding the company.

Now all of the debt thrown on the acquired companies is coming due and it could cause another economic disaster, even bring down the economy.

Going into the summer, it looked like the IPO market was poised for a resurgence. For example, the Blackstone Group (NYSE: BX) said that it planned on taking eight companies public.

Despite the enthusiasm, things haven't panned out. According to the Wall Street Journal [a paid publication], five of the last nine deals for October priced below their ranges. In fact, last week AEI wasn't even able to pull off its offering.

What has Blackstone (NYSE: BX) been doing with all those theme parks it's been buying? Well, the answer is becoming a bit clearer now. The private equity firm is getting ready to take theme park operator Merlin Entertainments public early next year.

Several investment banks have already been called to advise on the transaction, including Citigroup (NYSE: C), Goldman Sachs (NYSE: GS), Deutsche Bank (NYSE: DB), UBS (NYSE: UBS), and Nomura (NYSE: NMR). If all goes as planned, the deal could be good for $3.33 billion.

In the U.S., the prevailing sentiment is that the consumer is tapped out. And, even for those that have money, there will continue to be a good deal of frugality.

So, it would seem that theme parks would suffer, right?

Perhaps not. This is the thinking of Stephen Schwarzman, who is the chief of the Blackstone Group (NYSE: BX). Interestingly enough, he's doubling down on theme park investments, according to Reuters.com.

Up until the credit crisis, private equity firms had it made. They had plenty of leverage to play with and could load up their acquisition targets with it. So, they could realize a fantastic return on equity, mitigate their own risks, and show that they were the studs of the Street.

Then, all that went away. Credit markets dried up, and private equity companies lost their acquisition fuel. The numbers aren't as big as they used to be, but it looks like the private equity market is back in action.

The private equity industry has been through the worst, but now it seems the situation is taking a turn for the better. Stephen Schwarzman, CEO of Blackstone (NYSE: BX) expects deal flow and IPOs to bounce, saying the economy is showing "more than green shoots" of recovery.

Schwarzman, speaking at the Super Return Middle East conference in Dubai, doesn't expect another slip into recession, but the full recovery will take time, for all the same reasons you've been reading on BloggingStocks for a while: tighter lending standards; uncooperative consumers who won't spend beyond their means and so on.

The Blackstone Group (NYSE: BX - option chain) shares are rising today on reports that the buy-out firm is planning to unload a number of its portfolio companies, including TeamHealth, which provides outsourcing services for the health-care industry, and Merlin Entertainments Group, of Europe, which owns Legoland and Sea Life. Up to eight IPOs and five sales to private equity companies are in the works. If you think that the stock won't fall by too much in the coming months, then now could be a good time to look at a bullish hedged trade on BX.

Blackstone opened Monday at $15.50. In morning trading the stock hit a low of $15.50 and a high of $16.18. As of 11:15, BX was trading at $15.79 up 0.94 (6.3%). The chart for BX looks bullish.

In the U.S., the outsourced healthcare professional staffing market is about $50 billion. And, it is likely to grow because of the complexity of regulations and cost pressures.

One of the largest outsources in the market is Team Health Holdings, which generated $1.33 billion in revenues last year. In fact, this week the company filed to go public.

The past two years have been terrible for private equity firms. But, now we're seeing signs of life.

If fact, this week there was a liquidity event. That is, the Blackstone Group (NYSE: BX) and Lion Capital have received a binding offer to sell Orangina Schweppes to Suntory (a major Japanese drinks company). It appears that the price tag comes to $3.82 billion.

According to the Wall Street Journal, China's government recently has pushed development of its local private-equity industry so that Chinese investors can get in on the country's private-equity deals. To that end, Chinese officials have tried to lure foreign money managers to raise funds from local investors.

Hong Kong-based First Eastern Investment Group, which plans to raise six billion yuan through a new wholly owned Shanghai subsidiary, and Asian brokerage CLSA Ltd., which plans to raise a 10 billion yuan fund through a joint-venture with state holding company Shanghai Guosheng Co., are just the latest to establish local-currency private-equity funds in Shanghai.

Over the past couple years, it's been horrible for the private equity sector, right? Well, not so for the head of the Blackstone Group (NYSE: BX), Steve Schwarzman. According to the Corporate Library -- which put together a top 10 list for the highest paid executives for 2008 -- he was first on the list. The second was Oracle's (NASDAQ: ORCL) Larry Ellison, with $543 million.

When you add up all the sources of income (cash/bonus, stock options and restricted shares), the compensation for Schwarzman comes to $702.4 million. Just imagine if the market was stronger.

As seen on the Blackstone Group's (NYSE: BX) latest earnings conference call, the firm is trying to find ways to diversify its platform beyond buyouts (this is no fluke as other firms, like KKR, are doing the same thing). One of the areas of interest is actually hedge funds.

To this end, Blackstone made a big hire this week, bringing Byron Wien on board as the vice chairman of Blackstone Advisory Services. Actually, he is leaving Pequot Capital Management Inc., which is a hedge fund that is in the process of closing down (assets were as high as $15 billion). The firm is now faces an SEC investigation regarding trading in Microsoft's (NASDAQ: MSFT) stock. This is according to a report in the Wall Street Journal [a paid publication].

Here are some highlights from last week's earnings coverage from BloggingStocks:

• Activision Blizzard Inc. (NASDAQ: ATVI) reported better-than-expected Q2 results, sending shares higher.
• Blackstone Group (NYSE: BX) said it swung to a Q2 profit despite a dearth of leveraged buyouts.
• CBS Corp. (NYSE: CBS) Q2 earnings declined but still topped estimates, sending shares higher.
• Coinstar Inc. (NASDAQ: CSTR) reported stellar Q2 results driven by its the popularity of RedBox.
• Clorox Co. (NYSE: CLX) posted solid Q4 earnings but said revenues were flat due to currency effects.
• Duke Energy Corp. (NYSE: DUK) lower Q2 earnings beat expectations by a penny but revenue fell short.

Despite the credit crunch and recession, private equity powerhouse, the Blackstone Group (NYSE: BX), was still able to post a profit of $180.8 million in Q2. How was this possible? It certainly helped that the equities markets surged. The upshot was that the Blackstone company portfolio had an average mark-up of 3%.

Yet, the fact remains that the buyout business continues to lag. While valuations are attractive, the problem is that banks continue to be stringy with funding. Unfortunately, without leverage, it's pretty tough to generate strong returns.
