Because people are net removal of consumption, yes?
One more worker, 0.9 more consumers, such that supply of labour exceeds demand of commodities produced?
Well, reducing net consumption is a good thing for individuals. Because net consumption getting higher drives down per capita production, and what is actually available for consumption. Assuming your saying net consumption to be consumption - production
If consumption goes up, without an increase in production, then surplus goes down.
Say, for example, you have a stock of 500 houses, and 600 people looking for houses. In that case, the houses go to the top 80%, and the bottom 20% aren't able to afford housing, and have to rent a room or find other opportunities.
If housing consumption rises to 700, but the housing supply stays fixed at 500, then only the top 70% of people can afford a house, which now is probably a bigger chunk of their income as the 30% who would like to have a house put upward pressure on that house.
Likewise with Healthcare, education, or a great many other things. If consumption, or consumption demand, goes up without an actual increase in production, then things get worse on average for people as the same amount of resources are divided across more consumers (or simply a higher level of demand per consumer) with out an at least proportional growth in production.
One will notice that many of the things people complain about people being priced out of and thus we need higher minimum wages are specifically things that, at least under current arrangements, are hard to boost supply of: Its hard in new York for example to boost housing supply (even ignoring various rent controls) except at high expense, that expense including making what counts as a "house" progressively smaller.
Doctors is another one where I suspect effective averages have been going down, but Its hard to say because there's been such an explosion in doctor work between the 1950s and now: the rate has nearly
doubled, from 15 per 10,000 in 1950 to about 30 per 10,000, but given the huge explosion in things doctors can do, the % of the population who need more doctors time (because more and more things are more survivable, but with more doctor labor and long term care, and you have an older population), that the actual demand for doctors has way more than doubled.
For example, in raw "share of the population over 65", assuming the elderly are a big driver of medical care, the share of the population over 65 has increased from about 10% back then to around 15%. So just on how many old people there are, assuming the same labor intensity of caring for the old as it was in the 1950s, you would expect something like a 50% increase in demand for doctors proportional to the population. Considering the doctor labor necessary to tend to an old person is probably much higher now, and medicine is a much more bureaucratic exercise than back then, further driving up labor needs, I wouldn't be surprised that a conservative estimate for the increase in medical care per old person is double what it was in the 1950s which is then increased by 50% due to more old people, which would suggest meeting demand would require about 3x as many doctors as we used to have, while we have "only" increased the supply of doctors by about 2x.
And if you insist the doctors come from the top 1% of the most qualified, well, by the measure of x per 10,000, 15 per 10,000 already meant about 15% of the 1% were doctors in the 1950s. If you need something like 45 doctors per 10,000 to meet the new demand, well, 45% of your 1% being doctors is going to be crowding out an awful lot of other, potentially more valuable things, that you really would prefer your 1%, a very limited resource indeed, to be working on.
