I get what you want to say but on the other hand the 40 hour week - which is kind of the standard in modern capitalism - also ain’t it. Especially if you work in a toxic job you hate just for the money.
> that if you want to live a good life, you have to grind it out in your early years
I think if you have to “grind it out” you should probably look for something else. Meaning if your job feels like a grind don’t waste your life on it.
Having money is good but it’s not the most important ingredient to a good life
A 40 hour work week is not even half your waking hours. That would be seen a a luxurious life for most of human history, where you basically had to work dawn to dusk just to survive.
