I think generic metric metrics like GDP PPP have to be put into context. When I was in China I was shocked by how much stuff there was. Not even nice things, but stuff to the point most westerners would consider cluttered.

Rent was also super cheap.

On the other hand iPhones were pretty expensive. Enchiladas were super expensive too.

These aggregated stats have to guess what you’ll buy and base their estimate off of that. Your actual financial situation will be very dependent on what you need to buy.
