The Amish aren’t entirely in those eras - they aren’t anti-technology so much as very, very cautious about interacting with it. Many Amish communities these days are using things like solar power, pocket calculators, and other bits and bobs. Most of their communities allow phones, even smart phones, *if used for business purposes or required by a job". They make use of advanced medical technology, from organ transplants to something as mundane as glucose meters for a diabetic. Last couple times I took a train trip Amish in Chicago’s Union station were using computerized kiosks with no problem, and one Amish guy was showing an elderly English (i.e. non-Amish) couple how to do so. They use stuff made of plastic, synthetic cloth for clothing, and so on.
So no, even the Amish aren’t living in either the 1850’s or 1950’s.
But, like the Amish, we can choose what our priorities are. The problem is that collectively we’ve mostly decided on one set, when maybe a different set would have effects we’d find beneficial. Or at least different.
We could live more like we did back then, and I have friends who have adjusted their lifestyles to their incomes rather than trying to keep up with the Jones. There are one-income families out there, but they’re perceived as “poor” and weird, and they don’t have as many toys and fancy things. They lack social status, which can be a barrier to advancing in some careers.
People choose to have cable/TV app bills. They are not at all essential. Heck there’s even still broadcast TV.
You can have a minimal pay-as-you-go dumbphone instead of a smart phone. Of course, there is a LOT of pressure these days to do everything on a smartphone, it’s getting harder to avoid the internet entirely. So… you can have minimal smartphone and just use it when you absolutely have to do so.
You can repair your old car instead of replacing it, which is also easier if you do at least minimal maintenance on it.
You can still cook from scratch.
You can still mend your clothes instead of buying news ones. (It used to be cheaper to make your own rather than buy but that’s no longer true.) Instead of replacing my my main winter coat this year when the zipper broke I replaced the zipper. Cost me about $3 and some time, which is still cheaper than another coat.
The thing is, these are, by and large, NOT the choices people make.
