No, crimes exist for whoever isn’t in power. There are several crimes that can only be committed by rich people, such as those related to banking and the stock market, formation of cartels* and monopolistic/anti-competitive practices, etc. But conveniently the criminals are only prosecuted when they are the political or commercial opponents of whoever happens to be in charge at the time.

*Not the drug kind, the “a small group of companies with a combined market majority conspires to fix prices while pretending to compete with each other” kind
