All evidence points to a regime change (in the physics sense, not the political) being the necessary condition for things to go from our current state to something new.
We currently have people paying poorer people a very small amount of their own net worth to protect the wealthy person's status and position. This is similar to how kings and queens paid the army and policing forces to control the peasants.
Before the French Revolution I am sure it seemed impossible that the peasants would revolt, but the years leading up to the revolution things were getting worse and worse for the average peasant. There is a tipping point where the average person does not think the current system is delivering on the promise that of you do what you are told you can have a good life. I think we are approaching that point now.
If the rich try to hire someone and underpay them for security, stiff contractors for services, flaunt laws and generally behave obnoxiously at some point people will have had enough. Whether that ends with guillotine action or people just divesting from those systems depends on how much freedom people think they have.
If people thought they could go and homestead, live off the land, and get by without the massive companies these billionaires own then they would have that outlet and choose that peaceful option. The fact that we have taxation creates a pressure to pay in currency which demands earning in that currency. Same with paying rent, you have to earn money simply to live. No amount of growing all of your food gets rid of your financial obligations, so there is no out from the system. If that system is unreasonable it begins to feel less like participation and more like coercive control. Wage slavery is not the same as slavery, but both involve coercion and require the legal system to support them. Both lead to revolutions. Both lead to violence.
I guess the billionaires have to decide if they really want to paint that big a target on their backs by flaunting their wealth. At this point I think they feel untouchable.
