I've American but assume you are from the UK.
I suppose it is the same everywhere, but in the UK there is more of an opportunity for lower class people to live abroad. In Spain, Dubai (I know this) or wherever.
I had zero money staying in Earl's Court (I knew this place well as I haunted it as a college student). But I was happy in London. Broke or no.
And absolutely I am fortunate. I was not born poor, but I had problems as a young man reintegrating into USA society although I attained a college degree, never got addicted to drugs, never had a kid out-of-wedlock or the other things that really lock you into poverty in the USA.
I can remember Brian, the poor Irish-American kid who had the argument with me. I knew little of his background. I did know that he dated a girl from the middle-class & her father did not think much of him. I know little of him except that like many poor Irish-Americans in Los Angeles, his family were railroad workers (This was the big draw of Irish immigration to California, see). We never had any conflict prior to this confrontation & I hid my own semi-privileged roots (College degree paid for by my parents, grew privileged with vacations in Europe & African safaris etc.) Nobody really knew much about me (This was the days before social media). But Brian had come over as I was packing up to leave for the UAE & he looked like a wild, trapped animal: he had dropped out of school at age 13, probably because LA schools are so rough. He had zero social privileges. He may have been high. But he showed me his sheer envy & desperate unhappiness...I pretended to be flummoxed & have no idea what he was on about.
Here was the reality: I was glad to be going to UAE where there were no poor white Americans frustrated with their anonymity & poverty.
I was poor myself there but a) I had no kids or responsibilities b) I could leave & c) I had an education which on paper gave me advantage.
You are right. No arguments.
I shudder because for a TCK who had grown up going to Ambassador's parties, being invited to Sheikh's houses for dinner (Folks in oil industry) & traveling summers through London & Europe the idea of being blue-collar & working poor in the USA was a torment.
