This so much. I will never ever want to ruin my kid's life with such an expectation, I moved permanently to society where basic dignity is cca guaranteed if possible, and if it cannot be provided, so be it, death of me is fine and just a question of time. I wish to still being able to end it myself, on my terms, somewhere not bothering anybody, causing as little problems as possible (and settle will well ahead of it).
My useless last years are worthless compared to (remaining) prime age of the most important people in my lives - my children. What kind of piece of shit I would be to expect them to waste it on me.
Now is the time to live your life to see it as well spend, whatever it means to you. Then you can be dying in peace. You really can live off good stuff in life for a long time, and raising kids well is the ultimate achievement for me.
There is one issue with all this - I can't take such care for my own parents due to big distance. I can though easily pay for full support in any way they will ever require, which is still massively better objectively than me risking getting fired constantly and juggling their needs with my & my family. So the transition generation and those just before doesn't have it easiest, but I honestly believe this is the right, non-selfish way.
And if I succumb to dementia (which is never sudden), I will specifically beg all around me repeatedly that I want as little time & energy from them as possible, just a bit to cover their own emotional needs and happiness. Anything above is just a gift that shouldn't be too common.
