He is doing what is best for him financially. There were multiple issues that needed to be addressed that were ignored by previous administrations that Trump had a golden opportunity (no pun intended) to repair, and instead of using a knife to cut the fat off a bloated government, instead of just fixing a border issue that was essentially a layup waiting to be made, Trump got out the chainsaw and blowtorch and proceeded to **** everything up in the "repair" process.
Relationships lost or damaged, expertise in government gone, markets that disappeared due to unreasonable and arbitrary tariffs, the list goes on, you get the idea.
