That measure is wrong, it was designed to make USA look better. Read this part about the measure, it misses government subsidised healthcare etc:
> Household final consumption expenditure (HFCE) is not an exhaustive measure of the goods and services consumed by households. The general government and non-profit institutions serving households (NPISH) often provide goods and services to households for their individual consumption free of charge or at reduced prices. Examples are health services provided by governments or reimbursed by a social security fund, education services, the part of service provided by public museums, concert halls, operas, swimming pools that is not financed by entrance fees, aid for social housing etc. By adding the general government's and NPISHs' individual consumption expenditure to household final consumption expenditure one receives the actual final consumption of households.
Edit: Also another way to interpret that value is that is how much households has to spend to uphold decent way of life in that country. So it is really expensive to live in America so people have to work hard to survive. Of course you can't say for sure what is true, but if an American has to spend 50% more to live the same quality of life as a German person then of course he will be less willing to take vacation instead of the money.
A lot of Americans I know seem to associate vacation with super luxury trips. They don’t seem to understand the concept of just taking off and relax but instead want to do trips that go to five star hotels and spend 100 dollars on dinners. No wonder they can’t afford vacation. When I compare myself to colleagues I can often do a one week trip for what they are spending per day.
