I think many of these CEOs are evil and deserve to live in fear. However, they will just use their resources to delineate themselves from us deplorables even more. More security, more gated communities. Nothing will come of this type of vigilante attack.
The problem is CEOs have created their own monopoly on the market and hence have artificially inflated their value. The government can't fix it and will only make it worse with regulations. The general population can't do anything about it other than catch one of them out like Luigi did. How do you fight someone with $100 million dollars? I guess you make them live in fear which may or may not happen.
100%.
I am not inherently an optimist. I do think there really is a path to fixing it, and it goes through the government, but it doesn't
start there. We as voters and citizens have to come together to put politicians in at the lowest levels (school boards, city and county councils, etc) who are honest and intelligent and ethical, who see the problems and are willing to buck the system in order to work towards correcting them. Those efforts propagate up as those local politicians move up to more powerful positions, and eventually you have a base in place that can effectively resist the lobbyists and the big money and start putting us back on track. The alternative, like you said, is violent grassroots opposition, and even if that had a chance of being effective, it's a long and bloody road.
I don't hold out much hope. I don't think the United States as a people has it in us to fix this. We have to be a capitalism, but we cannot be an unregulated capitalism, and that means we can't be lazy. I think we're too soft, too lazy, and we will be too lazy until we see a couple generations of serious struggle and hardship again.
