Because if they lead to a higher salary and you can keep your spending habits the same, you have an option of having a stronger safety net, an option to retire at 45 instead of 65, an option to see Java the island and not only Java the programming language.
I live in a country where a strong safety net is the (current) default.
> an option to retire at 45 instead of 65
Retiring early is only a viable option if you do so in good physical and mental health. I'd rather spend my free time keeping myself in both, and retiring at 55. This is still entirely doable; even with the outrageous rent of where I currently live, I'm still able to save a third of my net wages, while not living very frugally.
Nobody dying is proud how hard they worked and how much they increased their market value.
I'm 100% confident that this is false.
