Duopoly’s produce excessive regulation as a means of protection.

Duopolies grow out slow growth, once the pie stops growing stealing customers is hard and is a zero sum game, reaching a comfortable stasis which then becomes the status quo is how organisms in these environments behave

> comfortable stasis

man, someone needs to disrupt the elevator business.

For example, why can't personal homes have elevators? The arguments of older people not being able to take stairs or getting hurt apply at home.

Or maybe busboys for groceries from the garage to the kitchen? Make them go sideways like the enterprise (the ncc-1701 enterprise)

Home elevators are a thing. We had one in our previous house, as did many other homes in the neighborhood. They are not terribly expensive, about $12k/floor during construction.

Not the US, but my dad just got one installed in his two story home, cost him around US$25k for installation of the lift/elevator itself, although he incurred a few grand more on modifications to create a space to install it in (would have been more but he did some of them himself). Not a new house, around 40-50 years old. In part, he got the idea because one of his neighbours had already done it. Plus his partner has dementia and climbing stairs has been becoming an ever increasing challenge for her.

We saw a new house with an elevator when we were looking, but it seemed to be an accessibility quota thing, I don’t want to think what it costs to maintain and what kind of inspections it needs.

Generally home eaevators are made of things that don't need inspections. Screws will last for decades without issues and when they fail rescue workers can get you out. Those systems are too slow and expensive for use commercial buildings but good enough for a short house. Thus commercial buildings will use a cable which is cheaper and faster but they stretch and break over time so you must do safety inspection. (a house sized screw is under a grand so not really a big factor in price, but that much cable will get several floors.

some commercial builings use hydraulic elevators which when they break just slowly lower you to the bottom floor . Again much less inspections needed because they are desirned safe. but the slow speed and cost mean only a few floors are possible

[h3xadecima1]

Cable systems are not cheap. The biggest issue with cables is the cores dry out. Hydraulic doesn't have to be slow by any means and they dont just seep down unless you blow a seal on the cylinder. Even then it would take an hour under a full load to move a story. Thats a lot of hydraulic fluid to displace. Hydraulic elevators are also prone to issues with cold temperature as the oil can become quite viscous when not in regular use.

[bluGill]

I was thinking a hose break not a seal which would fall much faster. Which is why you would design them slow - if a hose breaks they are still a safe fall. (of course if you make them fast then you need more inspection, a trade off)

That said I'm not an elevator expert. The details I've given so far is about all I know. So if/when someone claims to be an expert and contradicts me - well they could be right.

[brk]

Maintenance was essentially zero. No regular official inspections needed, but we had an elevator company come out every 3-4 years for a general inspection. Ours was a 3 story hydraulic unit.

[achierius]

I would ask kindly that nobody 'disrupt' the elevators I use to go into work.

[dietr1ch]

How can a duopoly produce regulation? That'd be straight out corruption unless someone came up with a new word for it that suddenly made that legal, moral, and efficient.

Lobbying has a pretty pronounced effect and is completely legal
