It's just a continuation of the trickle-down approach that's been concentrating wealth in the US for the past four decades.
The US was founded in large part as a revolt against British crown corporations. And until the mid 1800s, only public-interest corporations were allowed. But once the railroads had bought enough of the government, corporations got human rights, and the US was managed for their benefit.
Almost half of all Americans in the workforce are employed by small businesses. The false dichotomy between the interests of the individual worker and the massive, faceless corporation on the other hand is not tremendously helpful in this context.
I have nothing against small businesses, even if they're incorporated. I was a small business, in one of my careers. What I find disgusting is bailing out the wealthy, while barely helping the working class.
I don't know how financialization fits with respect to trick down economics. Particularly consumer financialization. They both seem to accelerate winner-takes-all processes.
