Plumbers are paid well because of the way they organized.

-They restricted the number of apprentices. That limited the number of people in the field similar to medical school.

-They could bar substandard workers from practising in the city of London.

-They kept their craft knowledge in house and it was never written down. Apprentices swore oaths never to reveal the “secret of the mystery.”

If you look at programming we do everything the opposite. It’s no wonder salaries will collapse. In fact the only question is why didn’t they collapse sooner.
