The problem is, I believe, that the federal government has gotten so big -- and so powerful -- that every corporation in every industry is flat afraid to confront them.
With the government positioned (and willing) to inflict greivous damage on a company's markets, operations and finances (and profits), there is no percentage in trying to defend yourself. Especially with the Democrats having brought political extortion to a high art.
Better to cower publically and lobby privately -- and pay the "protection money" -- than to come out fighting.
When we owned both Houses and the White House, corporate America was cowering.
