On CNBC today, Warren Buffett talked about politics, foreign currency – and oh, his financing of Mars's $23 billion deal for Wrigley (NYSE: WWY). He likes the deal for a variety of core reasons: a sustainable long-term business, strong management and the fact that the business is something that's easy to understand (chewing gum is fairly basic, right?)

Yes, this is vintage Buffett.

As usual, the deal started with a phone call to the oracle of Omaha, and he wasted little time in getting things moving.

Wrigley is the largest maker of gum and Mars is a large maker of candies, with Snickers, M&Ms and so on in its arsenal of products. In all likelihood, this deal will spur further M&A activity in the global sector. Such deals will help companies deal with spiking commodities' prices as well as the difficulties in creating new brands.

What's more, both Wrigley and Mars are family dynasties. The former got its start in 1891 and the latter was launched in 1911. Basically, for such firms to link up, it's important that the principals understand the complexities of family dynamics. And, for the most part, Buffett seems to understand such things. In other words, he is a value-added investor who takes the long view. More importantly, he has a war chest of over $40 billion. So as time goes by – and more family businesses look to consolidate -- I'm sure Buffett will get more phone calls.
