The purpose of the economy is to fairly allocate resources to people. Labor is a resource. If we suddenly have no scarcity of labor, that should mean everyone is wealthier than before. If the economy is crushed by suddenly having a limitless supply of a resource, it means the economy isn't able to allocate resources fairly, which is a problem with the economy, not the resource.

I'm an optimist and I think people can make the economy adapt to the problem of suddenly being richer than it was previously.
