Our society is not capitalist. New currency is constantly being printed out of nothing and pumped into the system. That's not a free market. Businesses just follow the money. It can be as inefficient as society allows it to become. As long as most people can ignore the reality.
If the banks were only loaning people money to collect sea shells, then the entire global economy would end up revolving around sea shell collection.
Then some rational people would eventually write books claiming that seashell collection is a bullshit job, we don't need so many seashells... Then people like you would post comments saying "That's not true, obviously we need seashells because capitalism would never allow for such inefficiency."
