The left is absolutely certain that people in general are too ignorant and stupid to know what's good for them. As a result, the government needs to establish guidelines for taking care of the otherwise clueless populace. The irony of leftist certainty on this is that the left shows itself to be clueless and stupid when it takes one size fits all governmental action intended to take care of everybody. What happens is that the government action makes things worse. Obamacare is an example of how it all works. Once the government program fails, leftists want credit for their good intentions and a follow on program to fix the unintended consequences of their previous programs. The cycle repeats until the government impoverishes the people to the point that there are not enough resources to pay for the programs.
While this is a gross oversimplification, it's still essentially true that Rome fell because the people got used to the government handling everything for them instead of doing things for themselves. Bread and circuses both bankrupt the government and corrupt the people. In the meantime, patronage and handouts buy votes. This cycle needs to be broken in 2016 or we are going to live through the bloody failure of Pax Americana.
