Modern unions have no spine and their leaders are in the game to enrich themselves it seems most times. This seems great for the rail union.
Every time i see US house members sleeping in their offices because they get paid so little for so much power, i shake my head at the utter obvious expectedness of the causal corruption that happens in Washington.
What's your definition of "modern"? It seems like most unions these days are doing a much better job than, say, Jimmy Hoffa's time.
Unions seeking out parallel power structures separate from the dominant government is a direct consequence of the government actively siding against labor at every turn.
