To most it's the opposite. Wealth is relative so I'd rather live in a 3rd world country making $50k than SF making $150k.
It was loads of fun and I enjoyed a lifestyle equivalent to earning at least $250k back in SF. Hotel room in the city center, maid service, bar night every night, motorcycle, valet parking everywhere, restaurants 3x a day, etc.

There appeared to be a lot less of that level of poverty in Saigon than in SF, but maybe that's because poor people don't live in the city like they do in the US. In any case, my presence there surely wasn't making anyone poorer so I don't feel bad about it.
In the Netherlands (where I come from) the average saleries for programmers are even lower, but in return you get a pretty great social system and a much saner work/life balance.
As for people living on the street. According to wikipedia the estimated homeless population in San Fransisco is between 7000 and 10000. The estimated number in Toronto is 5,253 (source: Toronto.ca), but since Toronto has 3.5 times the population, this means that the homeless population is at least 5 times bigger.
Compare SF bay area to Toronto would be more fair.
