I hate to be the bearer of bad news but 99.99% of all successful businesses and business owners are guilty of “shady tax dealings”. So that argument is a joke.
If you truly want to find some truth, instead of just cherry picking the bad press of a president that many hate. Read about all his successful business dealings. If you think him filling bankruptcies, cutting out on deals short term or defunding projects makes him a bad businessman then you are more confused on the subject then you probably want to realize.
