Large corporations and fascism?

In the NYTimes opinion pages this week, Tim Wu, a professor at Columbia, argues that large corporations lay the groundwork for fascism.

I don't think it's a very strong argument, as he fails to tie corporations to the actual rise of leaders. However he highlights that having fewer, larger corporations in an industry obviously consolidates political power in that industry.

He closes by stating: "We have forgotten that antitrust law had more than an economic goal, that it was meant fundamentally as a kind of constitutional safeguard, a check against the political dangers of unaccountable private power."
