Everything that happens in the economy is caused by people making choices. When there is a crash, it is because enough people chose to act in a way that caused a crash. If people lose their jobs, it's because someone chose profits over labor. There are no "natural" laws of the market. It is not a physical system governed by physics. It is a series of human choices. On paper, the market is a physics sandbox where there are laws of gravity and friction and momentum that all markets must obey. This isn't true. It's all people making decisions. If you can decide that profit is important above all else because profit is survival and prosperity for your business, then you can decide to value labor and realize that you don't have the resources to take care of your employees and aren't entitled to own a business. On paper, there's nothing the employer can do, they can only react to the market. In real life capitalists have agency.
