True. But, in our new world, not so easy.

People who have accumulated significant wealth either by inheritance or by good fortune have the choice to stay home and, if they choose, multiply that wealth by investing it. Increasingly, those investments are going into robots, AI, Machine Labour, etc. As soon as it gets cheaper to replace humans with automation in a particular field of work, it happens, squeezing yet another chunk of the workforce out of a job or at the very least creating a pay rate ceiling beyond which humans can't compete.

Raising the pay level for critical workers may temporarily help but it actually serves to speed their replacement with machine labour. We should do the former but must prepare for the latter.

For hundreds of years, we've built an economy that measures the value of work by the size of a paycheck and to some extent the value of a person's life by the wealth they've managed to accumulate. In a post-industrial economy we have to rethink that or suffer the consequences of rapidly rising poverty and social upheaval.
