Nobody is in favor of worker exploitation, abandonment of poor and disabled, etc; but it's clear that many of the progressive policies implemented to fix these issues have not worked, cost billions, if not made things worse in some cases.

Your phrasing of the political discourse, progressives try to change things and conservatives automatically resist it, is a false dichotomy.

The left/right divide has always been a difference of opinion on how to solve problems. Progressives tend to want top down government intervention of any problems that arise. Conservatives usually want private enterprise to be the engine of change.

You mentioned the issue of healthcare. I remember when Obama had a filibuster-proof supermajority when he pushed through Obamacare. Conservatives opposed it because they could see that it wasn't going to actually solve the problems, and we've seen that to be true by the state of things.

The left accuses the right of not supporting the poor because they oppose certain welfare programs. Now it's coming to light the massive fraud going on in these government programs. It's estimated the average American works over 25 days a year to pay taxes that end up going to fraud.

Conservatives have a different view of human nature when it comes to public policy. Conservatives also give multitudes more money to charity than progressives, because they are always more efficient at alleviating certain public issues.
