Why do people migrate to the british isles?

The British Isles, with the two countries based on them, the United Kingdom and the Republic of Ireland, are one of the most attractive places for migration for the people from the developing or less developed countries.

The reasons for the high interest to migrate to the British Isles is because the two nations on them are highly developed nations. The industry is strong, the wages are very good, the system works well, there's democracy, as well as relatively generous social programs.

For the people from the developing and less developed countries all of that seems like a perfect place for living, so the demand for migrating into this part of Europe is always very high.
