We all do. I have lost big time on individual stocks. But my overall portfolio is in great shape. Trump has never declared total personal bankruptcy. Only segments in his business empire have gone bankrupt. Bankruptcies are normal and necessary part of capitalism. It cleans out dead wood.
In 1991 or 92 he nearly declared personal bankruptcy. George Soros and the government bailed him out. That is nothing to brag about. Four bankruptcies are nothing to brag about.
His creditors have done terrible. You don't believe in honor and being a man of your word?
