You assume that he is working for someone else because you can't fathom anything else. You don't realize that one can put the time in so as not to have to work full time until retirement do you? Of course you don't because you have no vision or imagination. I know this because you have a broad brush perception of the world.
I have vast imagination... I just never met a manager who didn't lie to me, never met one who wasn't an arrogant jerk and never met one who wasn't largely clueless about what was going on under his nose.
And really if resume writing was a career you wouldn't need to work another full time job would you?
Well, except for the last six months I've been doing exactly that and making pretty good money doing it. And I don't even charge the criminal prices my competitors do.
If you were a burger bagger you'd be telling everyone that it's a job that needs skill so you can delude yourself into thinking you are better than you really are.
Frankly, have you ever been to a fast food place where they don't know what they are doing... they get your order wrong, they ring up the wrong price, and so on..
Here's the thing, you probably wouldn't last a week behind a burger counter. Your own co-workers would probably do you in.
