People don't need "cars, houses, TVs, holidays etc. We get them because we WANT them, not need them.
Any Robot that is smart enough to put us out of work will be smart enough to join a union and WANT a car, house, TV, Houses.
You basically suffer from paranoia, not logic.
But let's assume you are right. Let's assume that somehow, we (people) are smart enough to
1. Design and build robots that can do 50% of our current jobs
2. Keep ahead of the curve, upgrading all our robots faster than we upgrade our new jobs.
3. But still keep the robots from becoming self aware enough to demand luxuries, good working conditions, etc. etc. etc.
4. and keep it cheaper than a human Because at first making it smart enough to beat a human will be expensive, but almost immediately it will become more expensive to keep it stupid enough no to demand rights.
Even then, it STILL WON'T HAPPEN. Because humans have both ethics and hate technology. There are morons out there right now getting measles because they don't trust vaccines. We certainly won't trust robots that are intentionally kept stupid. We would instead assume they are just PRETENDING to be stupid and plotting a robot rebellion.
Watch any movie. That's how humans think.
