.....places like HK and Taiwan.....
Plenty of people in both places living in absolute shacks, and wishing they could eat a 3rd meal of white rice a day. Then you have America for example where food, medical care, and even shelter can be had free of charge. No comparison really, as I see it.
I'm not going to comment on Taiwan, but as Yoss points out, things in Hong Kong are a little different than you suggest.
A higher per capita GDP than the UK (with a top-slice income-tax rate of 15% [60% of salary earners pay 0% income tax and a family of four would need to earn @ US$ 50,000 before hitting the lowest rate of 2%], no VAT, no capital gains, no inheritance tax, no dividend/investment/savings tax).
A first-class, public healthcare system that's free of charge to those who can't pay and charged at nominal rates for those that can (US 6:00 per GP visit, US$ 7:50 per specialist consultation and US$ 13:00 per night for hospital inpatient treatment - these charges include all drugs, materials, operations, ancilliary care, etc.
There's a region-wide, cheap, efficient public-transport network (bus, minibus, train, underground, light rail).
Half of the total population live in public housing with monthly rents running between @ US$ 80:00 (for a small one bed @ 350 - 400 sq ft) and US$ 200:00 (for a 3 bed @ 1,000 sq ft). Free of charge for those who can't pay.
There is not a "shack" in sight and the total number of homeless peeps is precisely
zero.
Yes, we have problems with poverty and one of the highest Gini Coefficients in the world, but the last hillside "shack" in Kowloon was torn down by the late 1950's.
Times move on.
