The only solution I see at this point is mass protest and starting to assassinate CEOs, shareholders, and boards of directors, in self defense

Historically, terrorism isn't really a good way towards the elimination of capitalism. The creation of strong unions linked to communist parties (not in the "liberal democracy" sense of party, but in the communist sense) is a historically more proven way to fight against capitalist power structures. Unionise, create local dual power structures and mutual aid, join a militant communist party.
