I agree that the outsized influence of the rich and powerful completely distorts our democracy, but I honestly can't believe this is even being presented as a credible argument still.
Most rich people don't need the money, their own motivations drive them toward greater riches. I can hardly imagine someone claiming good moral character and ethics of someone with his questionable at best business and personal history.
You honestly believe big money didn't help him get elected? I supposed he just ended up with a cabinet of mega donors and billionaires?
