Money is relative based on what one can buy with x dollars. Standard of living is based on one's greed and lust; or on reasonable needs. There are far too many factors to say even if you specified country. Being content at 40k is better than being miserably insecure and inadequate at 80k because all your co-workers make more.

Given the AND in your question the only possible answer is the first worlder, as the third worlder cannot have a higher standard of living AND make more money out of the two.

Depending on the cost of goods of services for the third worlder, the answer may very well be "neither."

not really.
40k in the thirld world put you in the top 1% income earners in that country.

40K in a first world country isn't that bad.

doesn't matter. 40k
