The republican party idea is to never offer any tax funded support. This is difficult to push if success has anything to do with corruption or advantages you have as a result of having money due to who your parents are. To push this view and not have it come across as monstrous, the poor must be poor because they are lazy. Thus, anything that calls that idea into question must be vehemently opposed. I opposed the idea that the poor are poor solely because they are lazy.
The idea that the children of the wealthy and children of the poor have equal opportunity is laughable, but you have to support that idea for zeroing out all aid to the poor to not come across as monstrous.
