The problem isn't the "trade" ( window washing, painting, janitorial) it is the lack of using basic 6th-grade math and understanding you will be working for the rest of your active years.
If you know what your expenses will be after inflation, it is simply a matter of SAVING 10-20% of your weekly earnings and investing them wisely. It requires a pocket calculator and the ACCURATE knowledge you will probably be working for the next 40+ years and then be too old to work.
Believing Armageddon is any day now and you will soon pet tigers and Panda Bears forever is delusion....not logical, or solid financial planning. :)
As a senior, I am embarrassed to admit I was childlike, and I believed Watchtower BS for 50 YEARS !! It is like believing Santa Claus is real....as an adult. That is what makes me angry.
