Singapore 'still world's most expensive city'

Singapore has again been judged as the world's most expensive city but costs across the world have been highly volatile, according to researchers.

The question is not which country has the highest cost of living, but increasingly this body of life is increasing in some countries and other falling, This will cause the end between countries can not be sold because of the difference in life so that there will be unequal agreements.
By this I mean that thanks to multinationals makes the United States and Singapore in these cases are the countries with a standard of living much higher than others, which means that these countries earn more money and go to spend it within their country, this implies that these countries increasingly enrich themselves but because they export outside the trade but do not buy the pool and the other countries that have no benefits because the competition between companies are nules its cost low life.

this is happening today but people with beneficial factories still want more and more and this means that there is an inequality between countries large.
