I'd say most people want their country to "win" against others, they want to be richer than other people and want their country to be the richest sat the expense of other nations.

That's racism/xenophobia, isn't it?

Brexit seems to be predicated on the idea that Brits would rather suffer than risk the possibility that mutual benefit would be weighted towards others in the EU. That's pretty extreme racism (albeit founded on greed) IMO, and is endemic in British society AFAICT.
