I believe the answer you're looking for here is about CHOICE. Helping people shouldn't be forced on anyone, through taxes and what not. Individuals and churches used to handle all the charitable activity, but slowly the government started doing much of it. Thus, individuals and churches started doing much less. Direct ratio there.
As far as Trump, you can't compare Jesus to any human. He was without sin, the rest of us....not so much. Conservatives or liberals. Both are influenced by morality, but both groups are still people. Greedy people. Most conservatives want to preserve their own stuff, and liberals want more for them at the expense of conservatives. Neither one are any closer to Jesus than the ones they like to demonize.
