As you mention, I live in HK and have done for 12 years.
Yes, money talks here but there is a massive difference. Energy prices, communication, food, transport are all way cheaper than they are in the UK. The HK Gov has a large degree of control over energy prices as an example. In fact, due to the worldwide drop in energy prices, HK will see a drop of 7% in energy bills starting this month. I can't see that happening in the UK. I pay in about 3 months what many people in the UK pay in one month. OK, we don't have central heating but we have air conditioners and they're just as expensive.
When I get back to tropical Speyside (where I grew up), I'm shocked at what you guys are paying for things. Housing is expensive but there are bargains to be had, if you know where to look and, in my case, Mr Cookiemonster's parents knew a few people as well. I live in a 3 bedroom apartment in Tin Shui Wai, a few miles from the Chinese border and is not considered to be a desirable location (it's a nice part of HK with good biking routes and not as built up as some parts of HK), and I pay the equivalent of £1200 a month for it. Easily £1000-£2000 a month less if I lived the other side of the Tai Lam Tunnel. Which leads me on to another point. The HK Gov took all the tunnels back under their control and halved the tunnel fees. They just let the contracts expire and took them back in house. HK has quite a few of them, especially between Kowloon and HK Island. Can you imagine the UK Gov doing that? The privateers would have a fit.
Of course, HK is not perfect. There is a high profile campaign to deal with the poverty here in HK, especially with the elderly population (and I have to say, egged on by Beijing) as we have one of the most unequal societies on earth but there's action being taken, led by the younger generation, to deal with that. There's no VAT here in HK but there are signs that there may be 2.5% sales tax added to some items to pay for infrastructure projects but that does seem to be a few years away.
Another issue about your picture, Havana (Cuba) has been under US sanctions for about 70 or so years as the USA are still pissed that the previous leader, Batista, was overthrown and Cuba stopped being a Mafia state. So that's an unfair comparison.
Socialism gave the UK the NHS and the welfare state (despite massive opposition from the Tories) as well as education and plentiful (and affordable) housing. Capitalism has ripped that apart. You can have a capitalist society but with some restraints, as we have here in HK.
