Sounds like you have never had a job outside the office. Go dig ditches for a construction company for six months and you'll run back to your 9-5 "slavery".
A part of me misses blue collar work. I'm a software engineer now and love my job but I'm often mentally exhausted, have less time to think, and find it much harder to stay in good physical condition. Besides, in a lot of meaningful ways, it isn't so different. I work for a great company but that doesn't change the fact that I'm giving up a certain amount of practical free will and allowing others to profit off of my work. It's not slavery but it doesn't always feel so great. I've never understood the mentality you're exhibiting. Someone else has it worse so nobody should complain? That's nonsense. Everyone should strive for better. Whether they're at the bottom or the top. That has always been the way of humanity.
There is no mention of 9-5 in the parent comment. What made you get so aggressive at the statement above?
