Trump is happy to play golf, watch television, have the government pay for his extravagant lifestyle, get lots of attention and laugh at the angry, impotent people whom he intentionally offends. As an added bonus, no matter if a few people bycott his brand - he and his family still are earning far more. For example, Tiffany's copied crap now sells 10X as much as it did a year ago.
The Republicans will never impeach him as they can't risk losing Trump's supporters in congressional elections. Most importantly, they pay off their big business supporters by cutting education, medical care, food stamps, the minimum wage (in some states), allowing previously protected lands to be exploited, taking away women's rights, maintaining the flow into for-profit prisons with long, harsh sentences, making it harder for the poor and African Americans to vote, stuffing the Supremes with conservatives etc. They will use the savings on services for humans to buy more redundant military hardware and reduce taxes for the rich. He makes the news with his tweets and nobody seems to notice how rapidly the government is changing.
He is their extraordinarily effective court jester. Nobody is going to fire him, not even if treason can be proved.
