@OP "You spend years in school and night school taking classes and getting advanced degrees, years in an industry giving it everything."
Why did you do it? To have a better paid and comfier job. Instead of having to stop working at 50s because of the pains and destroyed health, you can keep working longer into your 60s. Instead of getting a lower paycheck and be concerned about money for years, you can be saving some money for later on. So if you took that extra money and blowed it away on vacations and living the good life, thinking the gravy train would last forever, that's on you.
I am prepared to work until I drop, but I have saved like I am having an early retirement. I have no debt, I have passive income, and I already got the benefits of my sacrifices. Whatever more I can squeeze from my studies and efforts, is just gravy.
