The attacks on labor unions has some merit, but not any where near what is claimed by the usual character assassins. We are a consumer driven economy, fair wages and benefits fought for by labor unions have what made America Great.
It seems some Pols and voters have forgotten the social problems which were created during the Gilded Age: Poverty and Violence.
The establishment of new boom towns during the gilded age, with tremendous cities like Akron and Youngstown and Pittsburgh and Altoona, growing like weeds always causes some societal discord. People come from all over to move to these towns, not all of them will make it.
The way that the problems were dealt with were with "settlement houses" and other self help organizations like the Knights of Columbus and Greek Catholic Union who provided insurance for injured workers, etc.
Big Labor's role in this was very limited, due to the fact they got their asses regularly kicked during their labor disturbances until their heyday in the Great Depression.
