"Both groups have little use for the middle class..."
Au contraire. The essence of liberalism is to funnel money from those who have too much money (those who have savings, that is, those who don't live hand-to-mouth) to those who don't have any. If I make $100K/year, I can buy an iphone and bank some money. This doesn't fit Apples needs. They want to sell iphones to people that don't have money. So to take some from me and give it to them. This goes for the phone companies, utility companies, landlords, etc. If Wall Street didn't need the welfare state, it wouldn't exist.
