I can't imagine how much money Trump (and his offspring) are making out of the Presidency. I mean, maybe that's really the main driving force, and all the "politics", no matter how evil and scary it appears, is, in fact, just window-dressing for the grifting? [That might actually be the best-case scenario]
Between that airliner, the opaque cryptocoin scheme, the tariff-driven stockmarket gyrations, the pardons he's issued to people who just happened to make "campaign donations" (why does he even need campaign donations given that he can't run again?) and so many other income-generating opportunities, he must be coining it in.
Not to mention the way he's used his power to suspend so many of the regulations that would limit possible grifts, which seems kind of suspect at least.
