That's... how investing works? The average S&P 500 investor is probably making even more money than that lady (in percentage terms), with even less work. If you're a landlord you have to deal the hassle of finding renters and fixing stuff, or hiring a management company who take a significant cut. If you're an S&P 500 investor on the other hand you pay vanguard 0.03% and they handle everything for you.

To be fair, if I was renting apartments, I would 100% never give tenants my contact information, and have them deal with some sort of management company. I'd rather pay someone else to receive the "oh shit, the pipes burst" phone call at 3am.
If you can outsource all of the effort to other businesses, but you still make a profit, then you're essentially just a tax on top of the service.
The main value add was capital to build the dwellings in the first place. If that capital didn’t exist, then the dwellings wouldn’t exist either.
The fact that the ROI of that capital is extending to multiple generations may be unpalatable, but it may not be unreasonable (lots of variables).
A secondary value in this case would be hiring a good property management company. Some of those companies really suck, and some are really good. As a tenant, you want one of the good ones. A silent owner who is willing to give a healthy rev-share to the management company is the type of owner you want.
In this hypothetical scenario, what I'm providing is the actual physical place that's being rented out, having put up the money for a down payment and the monthly mortgage payments, taxes, etc.
If this “somebody else” has the capital, then they should build or buy.
Obviously there is an issue of lack of purchasable land/units in certain desirable areas, but that’s a zoning issue. That’s not the problem and shouldn’t be the problem of someone who had the foresight to invest their capital many years/decades prior.
It may surprise you to learn that restaurant owners often hire cooks & wait staff.
Because you want to make money. You hire someone to do that shit for you, and you sit back and cash checks.
Most people who own restaurants don't like to cook or process orders, either.
They do it because they believe the effort and risk provides a decent reward compared to other available alternatives.
