Sure, PPP (Purchasing Power Parity) comparisions are important (e.g. it's easier to live in Thailand with $1000 per months than in NYC), but absolute values matter as well.
UK and American prices are around the same number but in pounds which meant ~1.6x USD at the time.
Are you sure about that? For a start, converting USD to GBP will make their money go not as further
Might be just general British negativity, they probably feel miserable at Disneyland.
No. I was just going off what parent said. I've seen way too little UK (mainly only London) and US (mainly only NYC) to judge myself.
I.e. sure when you go to the US and have to buy USD with GBP you'l be at a disadvantage, or when you buy some electronics priced in USD, but how big a portion of your spending is that compared to food/rent/commuting/hobbies etc., all of which are priced in your local currency.
This is only true when being a tourist though as you are thinking in your native currency and basing purchasing decisions in that frame of reference, when you actually live and work in the respective country then (ie if you move to another country) then that stops being an issue as you are earning in the new currency.
Thinking about it, I know a dozen or so people in the "poor deprived" north east of England earning over £40K who are under 30 years old so we're not all badly paid.
