RTO is way to force people work for two more hours per day for the same pay (1 hour typical commute one way). Hence it is done to suppress wages and make people leave voluntarily. It's not that hard to deduce.
But it is not, people work more when remote. It is harder to disconnect from work. This kind of bothers me because it seems RTO will reduce the hours spent working (on average) which should affect the output, but somehow companies expect the inverse.
