Back in the 60s and 70s, one could count on the Democrats having the working man's (and woman's) back. But all of that started to change dramatically around 1988.
Unions have been their own worst enemy by voting for democrats. Democrats support more things that hurt unions and other blue collar working people than any party that exists.
The Democrats have convinced you fools that if something is bad for business and corporations, then it is good for workers. Nothing could be further from the truth. Everything that hurts corporations and businesses will eventually trickle down and hurt the workers.
That is the true "Trickle Down" economics.
