That's certainly not true. We now have washing machines, dishwashers, refrigerators, kitchen machines, gas or electric stoves, food delivery services etc. All this makes carrying for others easier. Plus being more efficient at paid work could be translated into less working hours, thus more time to care for others instead of more money captured by capitalists.

Nope. Absolutely wrong. You can cook food faster than you could 150 years ago using microwaves, induction cook tops, non-stick pan and other advancements in kitchen tech. Modern care aids reduce the time it takes to wash a person, and allows them to wash themselves much later in life before they need partial or full assistance. Modern adult diapers come off easier, seal better, and absorb more, so they have fewer blow-outs and it takes fewer wipes to clean up a person.

Edit: let's also add that better productivity in other areas enables fewer people do more work, which (should) free up a larger portion of the population for elder-care.

You realize 150 years ago was the year before the telephone was invented, right? Most houses didn't even have electricity back then.

I was an in-home caregiver before COVID, and we certainly didn't have to warm water on a wood fired stove to bathe the clients with. I didn't have to scrub the laundry with a washboard, we had a laundry machine. I could call 911 without interrupting CPR, which wouldn't have been possible even 50 years ago.
