Obviously you have not researched his business history. His father left him 113 Billion dollars..... a huge fortune which has now dwindled  to 13 billion. Most of that is tied up in unrented properties. He has had 11 bankruptcies and has 14 court cases pending for various business failings. His work is done offshore and his US workers are immigrants, all the things he labours against. If that is not a failure than they best change the definition of the word.
