That’s because the mafia knows to be loyal to the underlings, and in return they’ll be loyal when put under pressure. They don’t care to do a jail stint as long as they/their families are still being taken care of.

You can’t be loyal to Trump, because he won’t be loyal to you. He knows enough about acting like a mob boss to be circumspect in asking people to do illegal things, but he’s too greedy and narcissistic to treat people like a mob boss. He won’t buy their loyalty so he doesn’t get it.
