I was amazed it was on Huffington, too.
There's one thing about large corps, though, there are economies of scale that enable competition and protection globally (as you say, small companies need a billion to fight 'em). I was upset when MetLife recently cut off their personal life insurance business into a new company -- Brighthouse. Why? They were the #1 life insurer, they have the leverage to compete globally and, most of all, they are Americans investing in America. Now, their cash flow and leverage is down, with 62B in debt and 32B+ in cash. Shoot, Gates and Buffet have more cash. But will they pay down debt with that? Doubt it, they never do. Maybe the "bright" went to Brighthouse
On a side note, they claimed to be giving us a stock dividend of one share of Brighthouse for 11 shares of MET. Yeah, sure, no dividend. The money for those shares came out of the balance in the MET account. Essentially, at the end of the day, the total of both amounted to the same thing, except the Brighthouse stock went down a bit.
I do believe monopolies like Google and FB need to be broken up.
