If working at McD's can be stereotyped with the phrase "flipping burgers", I propose that packaging things at an Amazon warehouse be called something like... "boxing dildos".

One actually handles food.

I took it as the total reverse.

yes, you and everybody else, it seems

It really isn't ambiguous at all, imo. He's clearly saying flipping burgers isn't skilled labour. Like that's literally what the sentence means, as he's comparing flipping burgers to "skilled labour", which he wouldn't do if he thought "flipping burgers" is "skilled labour".

He says he'll be "damned" if what he says are unskilled worked at McDonald's would be paid as much as him — who identifies as someone doing "skilled labour"

you're right. but I didn't expect everyone to have the opposite impression of what I had at first glance
