Since when did we become entitled to a well-paid job?
If, let's say, tomorrow they invent an AI that can write great code, putting me out of business - I will say, well, time to switch to something that pays. And there are still TONs of jobs that pay - electricians, plumbers, carpenters, construction equipment operators, elevator repairmen, illustrators, real estate brokers - they all make good money. For now at least.
Why would I even waste my time as a waiter? That time can be spent learning a skill that's in demand, not something literally anybody can do.
