do a quite calculation, if I make net $80,000, in the respective
countries, in their respective currencies, these are the tax I have
to pay,
Singapore =S $4,300
Australia = A$18,600
UK = £ 25,640
We have to look at the total
tax system of a country and not just one tax item in
isolation.
This is an overly simplistic view.
You need to take into account average salaries/wages (in their
currencies as well). However, this is still simplistic because
other factors like GST, petrol tax, average price of food, etc etc,
all comes into account.
Ultimately, as pointed out by M13, it's where the money went to
that counts the most.
