The problem with "that" capitalism argument is that it doesn't apply free markets rigorously enough.

In the near future, businesses will be destroyed for not being environmentally friendly.
(this is not synonymous with "green". One is a statement of an actual environmental impact, the other a political statement)

People want good, well built products cheaply. They also want clean air and water.

They also want clean money.

If we want to look at the most destructive corporation on the planet, we would be in the top 10 if we analysed the FED. It has caused more destruction of people's lives than anything i can think of (except all the other central banks combined)

However, this pales in comparison to the destruction that is the "corporation"

Corporation - a legal structure that allows profits to be internalized and costs to be externalized.

So, once this was set up in law, then the only businesses allowed to exist are those that externalize as much cost as possible. Everyone else can't compete.

Until now. Where we will start seeing ultra-low overhead home-based businesses that can continue when demand falls to near zero levels. The corporations will no longer be able to compete. Especially when the internetz will be pointing out their cost externalization (in specific, not in general. Transparency is coming)
