@KarmaCaramello yes, I saw that thread too. I’ve often found the AMA threads really interesting when they are about someone’s unusual job, life changing experience, wisdom or learning from something or expertise, but I’m not convinced that “my household income is £x AMA” really has anything to tell the rest of us whether we are richer or poorer or the same income level as the OP. It smacks of “let me dazzle the little people with my DH’s income and the choices it gives me”. As for the incredulity at causing upset; they are either out of touch, insensitive to just how much people are struggling or have a misplaced idea that high earnings and high outgoings mean they have the same worries and juggling act as someone on a low income - they really don’t.
It reminds me of the kind of threads that irritate me “I earn £x, is it enough to live on?” Firstly, who knows? Depends on your expenses, location, attitudes etc. also these threads just encourage responses coloured by the income, expenses, location and attitudes of the responder. No one is any the wiser about the OP’s financial situation at the end of it all.
In the case of “DH earns eleven billionty pounds a year AMA” I just can’t think of anything to ask as it’s entirely irrelevant to my life and just not very interesting to read the revelation that they have an income and outgoings and cut their cloth accordingly, as that’s what most of us are doing anyway (at whatever income level). I could start a thread saying “I put the bins out on a Tuesday night AMA”, it wouldn’t have any less relevance really.
