London is one of the most unequal cities on the planet. You get this surreal mix of wealthy billionaires and poor migrants living hand to mouth. The upper classes protect and segregate themselves from the riff-raff through pricing. My experience was that London is not actually a community, the cultural and socioeconomic rifts are so profound that random people seldom interact, there is little small talk to be had with strangers.

Tourists thoroughly enjoy the central areas but seldom realize they could never afford a home there of any decent size.

I'm pretty sure that title would go to the capital of some banana republic whose elites are probably living in London the half the time anyway.

yes, having spent a couple of months in India I doubt London has worse inequality than tier-1 Indian cities.

London is a rich person's theme park to which tourists are permitted some restricted access, for an exorbitant price. ("tourist" includes people renting for the short to mid term, who simply could not afford to buy, and will move out of London to do so)

Most unequal on the planet? That is ridiculous. Even SF with its thousands of dotcom millionaires and thousands of homeless is worse, let alone places with proper inequality like Mumbai or Lagos...

Ealing has some upmarket areas.

For the roughest and poorest areas try Harlesden, Tottenham, or Edmonton. (Or don't, because they're dangerous.)

That's not a complete list, but they'll certainly give visitors a different view of London.

"regular" or "poor"?

I would argue that the neighbourhoods above are just representations of the other side of the spectrum. Not where "regular" people live.
