With $40k a year you can live with the rich in some Latin American countries, if you can also spend 250k/350k on buying your own place in a high rise with private security or a gated community. You won't have access to Amazon and be able to buy all the top notch gear for your new hobbies in a week like as a tech worker in the US, but you can have a nice house with cleaning staff, a nice car or just take Uber or private cars everywhere, and do fancy dining two or three times per week.

The median American household doesn't have all this luxuries.

Yeah but I'm not trying to struggle in America, so cómo estás ¿
