Ok. You basically said that republicans were fighting against people getting living wages and healthcare. That's not true. Healthcare is provided for the poor and old and other safety nets exist for low earners. Republicans simply don't want the federal government to expand even further into our free market, capitalistic society.
And of course $15/hr is an absurd minimum wage. The pimple-faced 15 year old tearing movie tickets or sweeping popcorn doesn't need $15/hr. And if you are a functioning adult and can only earn minimum wage, the problem is you, not the government.
But then again, that's probably just my white privilege talking.
