I don't think it's a tax bracket thing, or even necessarily a culture/upbringing thing --> I was brought up white-collar working middle class -ish (Eastern European middle-class, which probably doesn't map cleanly to North American middle class; buying a bottle of coke was a Birthday thing), but then was refugee from a civil war for a while, with the appropriate tax bracket. And my grandma certainly instilled much of the same sense in me :)

Thing is, today, as an adult, I'm painfully aware that I'm mortal and life is limited and time is the most precious resource available to me. I'm not religious so I don't believe in after-life reward for being a good boy either. So I'm a little bit more mindful / little less self-flagellating, than I used to be, about these things.

For myself in particular:

* Yes, I shower and wipe my own bottom :)

* I am the dishes and laundry queen in my family, though I definitely use laundry machine (curious where that would fit in your matrix btw? :)

* I don't mind the act of lawn mowing but I absolutely resent the randomness of it - at some point north american society decided that we/they will 1. Adopt a very specific fast growing grass for ALL the lawns and 2. Having it more than ~5cm long is an affront to man and god and neighbourhood alike. Why they haven't just culturally picked cloverleaf or something is beyond me

* I like organizing my living space but I get zero sense of satisfaction out of vacuuming, dusting, and general maintenance. Many other people love it! In turn though, they probably get zero need to constantly rearchitect their home network like I do :->

In sum - I personally put laundry machine and auto-vacuum in very different category than showers and wiping bottoms, but if you lump them together, much power to you, though I don't think it's a tax bracket thing necessarily :)

The way I see it is: My time is worth $0 unless I'd otherwise be earning money.

So if you're an hourly contract worker, and you would otherwise be billing $100/hr to write code or something, then it makes sense to pay a gardener to mow your lawn and a plumber to fix your toilet, as long as it's less than you're making.

But instead, if you'd otherwise just be doom scrolling on your phone or jerking off, you might as well mow that lawn yourself. Paying someone any amount of money is a waste.

I pretty much DIY everything around the house. I work hard for my money, and it feels lazy and wasteful to just ship it off to someone else to do what I am fully capable of doing myself. Maybe when I'm 80 and have trouble walking, I'll pay someone to move furniture around or wash my roof. But not while I'm able bodied.

I have a bidet to help wipe my bottom... It isn't enough that I can skip wiping completely, but it greatly reduces that chore.

I sometimes dream of being rich enough to afford a servant to do this for me. But realistically even if I was that rich I wouldn't subject someone to that indignity.
