A key difference might be, Hutong stays as Hutong because the government specifically wants to preserve it as a homage to the city's history.

We have bad conditions for sure in San Francisco and poverty elsewhere in the US that all Americans should be ashamed of. Frankly the state of poverty in America is unacceptable. But the poverty we have is nowhere near the scale and absolute horror of Mumbai slums. I've traveled extensively through South America and seen horrific conditions there but nothing was as shocking as Mumbai slums.

I find posts like yours are misguided and demonstrate total ignorance regarding human suffering.

Having traveled extensively as well I agree nothing compares with the slums of Mumbai. But the bad areas in America carry an extra connotation of crime and drug use that poor areas elsewhere may not. I didn’t spend any time in the slums of Mumbai, only observed from afar, but I suspect I’d feel safer walking around them than the bad parts of SF, LA, Baltimore, Detroit, etc ...

That's because Mumbai slums are not just slums, but come with the whole racist ideology (low caste, etc).

Sounds like SF.
