One of my friends opined that if most people (limited to people on this forum, let's say) rationally priced in their future earnings, they'd be in debt more often, for longer and earlier in their life. The naive algorithm of "save as much as possible" might land high-earners with a huge nest egg they end up carrying to their grave. I think I agree with that.
Savings allow you freedom from having to earn money, the opposite of debt. For example, you can temporarily "retire" for a few years and do what you want without pressure. Either directly or indirectly, I think having debt limits you to the path & earnings you've "forecasted" - the opposite of freedom. At least that's the case for me.
Not everyone strives to min max their time to the extent that they _can't_ be working while doing what they want. Assuming you're a white collar worker in tech, there are plenty of opportunities for you to make oodles of money, while having a balance between a job and life. Given the choice between being mortgage free in my 30s with an apartment in a cheaper part of town, and being able to quit work to travel/work on my carpentry for 3-5 years, or having a balanced life over the next decade, spending time and having experiences with family & friends, I'll pick the balanced lifestyle every single time.
