The only real takeaway is that Trump is a very astute businessman. We knew that already when we elected him.
I’ve made and lost significant sums over my lifetime. First of all you have to have the capital, yours or borrowed, to lose it. Second after my first disaster my advisor said you lost because the market changed. Right just lice Atlantic City where DJT got crushed: the market changed. The important thing is neither he nor I gave up and groused about it. That is what I admire not those sniveling cowards nipping at his heels.
