Income Tax and living here
Kuwait IS TALKING about a 10% income tax. There economy appears far different than Dubai's. Kuwait is heavily weighted on oil and foreign companies pay 55% tax on profits. They are wanting to REDUCE the burden for foreign investors and hence they are considering the income tax.
As for costs insurance on a $43,000 vehicle is about $140 a month.
Groceries- a lot of stuff is cheaper here, than in the U.S. and
internet costs as stated are more.
I don't see all the "high prices", but maybe it depends are what you are used to.
