Some corrections... their wages (in HK) are high ( for expat terms only )
.
Their currency rate is about 6 times
lower than Sing Dollars.
The living standard
(FOOD) is ok lah...
about the same in Singapore.
But many HK-ers love to eat at restaurants (at most of the
times, you need to share table with other
strangers). 
They don't have many kopitiam or centralised foodcourts. Mostly
are individual food stores.
Transportations - their MTRs are very efficient, 1-2 mins per
interval. So practically no need to buy cars.
The few thing which is EXPENSIVE is the rental
+ property living, parking etc. The lease hold is 50 yrs
compared of Singapore's 99yrs (for govt housing).
Their taxis' fares are reasonable though... Meter jumps by 30
cents (no midnite/peak hrs surcharges).... only took
twice...
becos their MTRs are very convenient.... No
Breakdowns ( when I took them )... 



And their foods are damn nice...To what I observe, Hongkees, being
brought up without a real identity, from british to china to
Special zone, they takes the hard knock of life better than
Singaporeans, and they are more homogenous in a sense, meaning they
are one race and is able to cooperate and help each other, ours are
more individualistic.
The HK taxi driver I talk to also told me, unlike our sg govt,
who feed their people and expect them to submit, Hk peoples are
left alone to find food for themselves, so since young, they are
very independent and have to find food for themselves.
After he dropped me, I told him there is a fare to pick infront,
he said, boss, this is not my playground, Hk taxi got own set of
rules and regulation, and of course, secret society.
