I'm not suggesting that you're arguing against the entire capitalist system. If you look back to what I wrote, I was just warning you that a wealth tax taken too far would destroy capitalism in a much different way than an income tax taken too far. Specifically, capitalism is about leveraging massive ownership to create new wealth. If you sufficiently disincentivize ownership, then capitalism would die.
That's an interesting concept but demonstrably wrong.
Up until the 1960's those earning over $400,000 pa in the USA were taxed at 91% and yet there were still people happy to go out and earn more than $400,000 pa.
To argue people would suddenly stop wanting to build businesses, invest and otherwise create wealth if we taxed wealth instead of realised income (GASP!!!) is simply not supported by past history.
People have been building wealth long before the idea that to tax the wealthy will destroy the world as we know it, or at least Capitalism entirely, gained popularity.
I agree with you that the productiveness of capitalism doesn't excuse the failures that you mention. But on the other hand, I know that every human system, no matter how finely tuned, will have some failures. The mere presence of a failure does not prove that the system should be replaced, or even that it can be more finely tuned. Given that capitalism is the greatest engine of wealth ever conceived, and that the US is among the greatest wealth-producing nations in the world, given that this wealth produced has raised standards of living for all people, I am inclined to approach the idea of changing these systems cautiously.
My question is not whether the current system is flawed, but whether we can knowably produce something better. What is an example of something that has worked, and what would be the path to getting there?
The US went off and declared independence and fought a war over it, then set up Capitalism as we know it today, all without knowing it would produce something better. Why now the need to tread wearily and not rock the boat and heaven forbid try to make things better?
History is littered with examples of societies implementing change without the certain future knowledge that everything would be better as a result of that change. In fact, amazingly enough, knowing the change absolutely will produce something better is simply not possible. Yet it has never stopped anyone before.
Furthermore, change doesn't have to be abrupt and absolute and complete transformation of one thing into something entirely different. It can be incremental and a step at a time and if the results show no improvement the changes can be undone. That process too has been happening throughout human history.
