Does it matter?
If one millionaire loses out to a billionaire on a housing project in NY city, it could have a HUGE impact. Why? Because the billionaire is just going to stick the money in his bank account. With Trump it's even more of a difference because Trump doesn't always pay those who work for him, then sues them. The millionaire might get a but richer, might pay more for the workers, might spend that money in NY city and contribute to the city more than Trump would.
Trump benefited from FRAUD. That's ILLEGAL.
Why do you think Trump should be able to get away with crimes? If it were Biden's son, you'd be asking for the death penalty, or worse
