I've been keeping these kinds of hours as a software/hardware engineer since 1977. Early on, it was more hardware and teaching microprocessors courses at the local college. The extra income allowed me to pursue and earn a fixed wing private pilot license.
I have been a net taxpayer every year since age 16. Taxation steals between 50 and 60 percentage of my earned income. Obama's crash of the markets wiped out half of my 401k, so I'll be working longer than I wanted. No big deal. I still run harder and faster than anyone else on the program. As long as I can tolerate the hours, I intend to keep working at that level.
Awesome post. For me, Retirement was always something the Dems created to take more taxes and line their pockets in the senate.. banking revolving door. It’s not Biblical. I’m can see the need to go part time after 70, but that’s about it.
