I would argue there is no such thing as an ethical billionaire. So yes, above a certain point, all rich people are bad. They hold an unusably vast hoard of resources. They elect to retain these resources rather than help others. Granted this is a subjective argument, but a sound one.
As for not being able to prove the danger of poverty, and my statistics you can rrad the research paper I pulled them from ar you leisure: https://jamanetwork.com/journals/jamainternalmedicine/fullarticle/2804032
Comparing “most people” to billionaires is ludicrous in terms of spreading the wealth. The average American makes between 1 and 2 million over the course of their entire life. So if you have 1 billion, you have 1000 lifetimes worth of money. Musk is worth 342 billion. The amount of wealth trapped in the 1% is absolutely preposterous.
As for your villainizing of “drug addicts”, try to tell me wealthy people don’t abuse alcohol and prescription drugs, and cocaine. The only difference is when they kill a cyclist while driving drunk they get a reduced sentence and it doesn’t ruin their lives.
