Well, I think you are right at some point. 9-5 job is just for day to day survival, at least it looks to me.
Someone needs employment and they go into it, cashes out salary per month to feed family and wait for next month to arrive.
Life isnt straight line, if we do what we do each day for living, we arent actually improving. To improve, no way out to hustle and search out a better angle.
Thats my viewpoint.
