“In general, Donald Trump is notoriously uninterested in policy details. It has long been obvious, for example, that he never bothered to find out what his one major legislative victory, the 2017 tax cut, actually did. Similarly, it’s pretty clear that he had no idea what was actually in the Iran agreement he just repudiated.
In each case, it was about ego rather than substance: scoring a “win,” undoing his predecessor’s achievement.But there are some policy issues he really does care about. By all accounts, he really hates the idea of people receiving “welfare,” by which he means any government program that helps people with low income, and he wants to eliminate such programs wherever possible.”
