A former McDonald's staff and manager here.

I worked at my local Mcds as a teenager in 90s London.

I readily recognize all of the jobs that you have described so powerfully; I did all of them.

And when I became a manager, I must confess that I became extraordinarily skillful at getting people to do those jobs in good time, while saving millions of pounds.

My salary as a manager paid my tuition fees at Uni, didn't have to take a loan.

If you want a crash course in how capitalism works and functions, Mcjobs is the greatest teacher; even more so than fordism.
