Footballers (in the PL certainly) could easily choose to take a pay cut and help the NHS and/or non-playing staff at their clubs. They choose not too and hide behind the ridiculous argument put up by a multi-millionaire crook at the head of the PFA.
You are quite correct that it's not the responsibility of players to fund the NHS and they are making it very clear that have no intention of doing so.
PL players are greedy, uncaring, self-important spoilt brats. And that's the polite
They’re not. But hey, I’m sure you feel better for feeling morally superior and that’s what’s important to you.
