> people lose their jobs etc.

People losing jobs doesn't have to be a bad thing.

What's worse, having them lose jobs and then we pay them for doing nothing / coming up with doing something useful?

Or paying them and they stay in their useless job?

The problem is that society chooses to stop paying the people who lose their jobs because 'it was their own fault' or something... And then people don't want to lose jobs but they keep doing stuff that's useless or even detrimental to society.

The bad thing happens is when people lose jobs but those were useful jobs.
