Been reading this thread with interest as someone who actually lives in the US as a Brit. And while, yes, wages are 2-3 times higher here in general - most commenters seem to have no idea how expensive life actually is in the US.
And so many parts of life here cost WAY more than 2-3 times what they do in the UK. So here you go, for those wondering -
*Groceries - we shop in the cheapest supermarket around and don't drink alcohol and spend around $200 a week for 2 adults and a toddler.
*Kids activities - 45 minutes gym or music class, or playspace access - $35 (plus tax!)
*Full time daycare for my toddler - $3700 a month, and don't forget annual gifts and tips for the teachers expected to top around $500-1000 each year.
*Renting a 2-bed apartment in a non-central part of my city - $5,200 per month (and again, need to tip buildings staff out 1,000-1,500 at christmas, and it isn't optional).
*Toddler haircut - $65 cheapest including tax and tip.
*My recent miscarriage - cost us $3,247 out of pocket (and we have the "good" health insurance). Our deductible is around $6000 per year.
*Flights to other parts of the USA - minimum will be $250-300 per ticket - cheap flights don't exist here really.
*Eating out - at least $50 per head at a lower tier restaurant and all prices have a extra 30% on what you see once you factor in tax and tip (min 20%).
Other stuff we pay more for - monthly preventative medication for my dog ($45 compared to 13GBP in the UK), internet is around $100 per month.
OH and let's not pretend labour laws are remotely a thing here. My partner could get fired at any minute and we lose our health insurance. So (just to be sure!) he works from 8-6pm each day minimum, but frequently stays up until 1am working, starts at 6am, works weekends or whatever.
Anyway my point is basically that the standard of living here really isn't much better, and the level of poverty and related crime and so on is significantly worse than the UK.
An other point - since when did the meaning of middle class change to mean literally spending power? When I was growing up it was related to cultural capital, education refinement and so on.
