The US Chamber of Commerce now represents fascism, not free enterprise. That is how corrupted our system has become.
I think their only issue is the unlimited flow of cheap (illegal) labor.
Just remember that fascism has been the endemic disease of the American economy ever since the days of Andrew Hamilton. Henry Clay's "American System" of high tariffs and "internal improvements" (i.e, pork) was the 1830s version of crony capitalism. Lincoln supported Clay's ideas. Herbert Hoover, as Secretary of Commerce, organized agreements among business and labor leaders to fix prices and wages and divide up markets. Franklin Roosevelt's National Recovery Act borrowed heavily from Benito Mussolini.
Fighting against domestic fascism has been a problem throughout the history of this country.
