The first paragraph actually is not contradict. It's necessary for government to promote new spots. But goverment shall not intervene mature industry, especially not help 垄断竞争 or 寡头竞争. Rather, US spirit should split those.
Entitlement is the biggest slice. But may not be the biggest increase, with Obamacare as exception. Yes, those stimulus are useless and at times the opposite direction, like "increase minimal wage". Obamacare is the direct reason for big companies like Olive Garden to reduce employee hours to under 30h/w and hire lots of temp.
Yes, at certain point, have to touch entitlement.
