> if AI and robots end up replacing most jobs

The only way AI and robots end up replacing most jobs is if they can do them for less money than people can. Which in turn means that those things become less expensive, since that's the thing causing suppliers to do it.

So there are really three possibilities here. First, we get robots that can e.g. build houses and housing scarcity goes down, so now you don't need to make much money to afford rent. Second, robots still can't build housing, so then you get a job building housing and have a job. Or third, robots still can't build housing but we have a bunch of rent-seeking incumbents that won't allow you to get a job doing that either, because they're trying to keep rents high or artificially limit the supply of trade labor.

It's the third one that really screws you and is the one that we need to prevent.

Let's say 50% of all jobs are lost. What would that kind of oversupply do to pay rates and working conditions in the remaining sectors?

I don’t want a house built by people who are just trying to get a paycheck because they got laid off from their cushy office jobs.
