How do you figure that something that is around 7 times less expensive not much cheaper. What qualifies as much cheaper to you. While I lived there I had a cleaning lady that bought all my food did all the cooking cleaning and laundry. I paid her 60 dollars a week. That covered all the food and her wages. And I ate very good. I spend more than that here in the US and I have to do all the work.
Do you really not know why high tech stuff is not cheaper there. It's because it is not made there. Why would a company like Apple or Sony or whatever company charge less for there product in different countries. It costs them more or less the same to make an iPhone no matter where the thing it is sold at. It's common sence really.
Things that are made there like some clothing and other goods are much cheaper because the companies don't have to pay as much in labor.
Yes I am well aware that there are some rich areas in the PI but what you don't seem to understand is that none of that cheap PI labor went into building any of those nice cars so why would they be cheaper. This is not really a hard concept.
