What is the suggested alternative to a market economy? Command economies aren't what I would consider better for the globe. Energy intensity per unit of labor is almost universally lower in market economies than it is in command economies.

A market economy would be fine if it's impact on the ecology was priced in.

There is no alternative unless we magically have free energy. The only way out of this is to colonize the solar system, galaxy. At that point the Earth's status as a habitable planet will hardly matter.

Worst thing possible? Really? That's a simpleton's view about existence. Countless planets die every day. I only care about the next 20 years I'm going to be alive for. I don't care about the planet or the survival of your children. Don't force responsibility on me.

So capitalism it is for me.

This is the capitalism mindset and this comment is proof that its the worst thing there is.

A bartender once made me an Old Fashioned without muddling the sugar. Are you certain that’s not worse?
