For example, if you live in a place where people make $12,000/yr, on average, then earning $24,000 is a nice living. In the US, software engineers often make north of $200k/yr, but a single family home in a lot of US cities is $500-800k, putting a new roof on your house costs $15-40k, and a dinner out at a sit-down restaurant costs $30-60 per person. If you earn $24,000, but it costs $8 to eat out and $80k for a decent house, that's not too shabby.
