I am not sure it is double or even triple standards right now.
I mean, it is what it is, and the natural progression of recent (the PL becoming the super rich destination of choice, also for investment reasons) and more recent geopolitics (the Brexit forcing the UK to find any alternative route to keep or increase its worldwide relevance) imho.
Triple standards because no big club fans, domestic or foreign, can really keep the high moral ground any more: it is uber-capitalistic football vs grassroots football right now… with UEFA and FIFA just acting as interested parties themselves, the former partnering with Qatar/PSG, the latter counteracting with 2 years WC projects and similar bs.
What can we do, really? Just stop following big club circus and stick to our local, amateur, Sunday league teams.
