That would still mean you're spending far more for food in a month by eating at McD, than you would preparing food yourself.

The price difference per region is irrelevant, the fact his statement is idiotic and ignorant applies for every region.

Besides, McD in Europe generally pays an actual livable wage to workers, not so much in the US. There's a variety of reasons for the price difference to exist. But again, the price difference is completely irrelevant to the point he was making because no matter what region you're in, eating at McDonalds isn't "cheap" compared to actually making food yourself.

Which is what people have been complaining about to have gone up considerably in recent years.
