Not directly related, but can we also seize Kevin O'Leary's assets and fire him out of a cannon into the sun?

I agree we need to tax the rich more. But where do think that money sits? It's not in a checking account. It's in shares of companies and other investments. If the rich are forced to pay billions in tax, they have to pull money out of those things and that causes real operational reductions - ie layoffs and less productivity- and that means less product available to consumers - and so prices rise. It's a complex interplay of issues and not really as simple as just 'tax the rich'. Not saying we shouldn't, but we have to do it carefully. Oil and gas subsidies are pretty short sighted, it seems, but why do you think it's done? It's to get international investment and productivity higher so people have jobs, we can buy things that we need from other countries and have produced resources for ourselves.

The problem is that we simply can't throw our economy away. It would lead to disaster even quicker.

Well if we're so bad, maybe it's good that we go extinct?
The economy just is a part of society and is the way we organize resources. The way our capitalist society works, money naturally keeps moving upwards and screwing the poor - it needs strong regulation to work in a way that is beneficial for most people. Canada is better than the U.S. there. But there are realities that require society (and the economy) to continue to operate in such a way that allows the country to provide for its citizens. If the economy burns and society collapses, which you seem to want, then there will not be resources available to support the people. And any semblance of regulation that keeps lawful order and social safety nets will fail. And at that point likely some group will take over and then do whatever they want - without any regulation. So probably worse for the ecosystem.
