Yeah, I’m aware. Monthly (very basic tho) food is $40–$80 (converting from local currency) per person. Rent is $200–300 for a 2 bedroom basic apartment.
At the same time, “luxury” things are way more expensive here. Smartphones, computers and cars, for instance, are almost 2x the price. Shoes and clothes that are beyond expensive here are normal in the US.
So our cost of living is way cheaper, but our purchase power is lower still. If you can work remotely, you are paid in dollars, and can travel to the US to buy things, you can live a very comfortable life here with an income that you would struggle in there.
PS: I’m using $1 = R$5, which is not true, because our currency is dying. Using more updated prices only make the discrepancy even greater
