The Republican leadership tend to be terrible when it comes to their economic policy that benefits the rich more. I understand that a lot of rich people may own businesses and create jobs. But while Republicans tend to want to loosen regulations on the money for the rich (tax loopholes, tax breaks, etc), you find them increasing regulations on the poor by making it harder to get social services and benefits (unemployment benefits, welfare, etc.). It's no secret that the Democrats tend to make it easier for the poor and middle class to get money. Hek, even when it comes to college education costs, you tend to find more Democrats pushing for tuition-free college than Republicans. I believe that making it easier for all to attend college and trade schools would be a huge positive for any society. I've personally gone from the somewhat poor to middle class all because of education.
I have several other problems with the Republican party, like how they tend to not give criminals second chances, but I'll probably leave that to another post.
