In the case of numerous colonies, why didn't the British Empire move to North America as a whole?

Before the United States developed, Europe was the center of the world, and Britain, as the world hegemon, would definitely base itself on Europe, the home of the world center, and would not move to distant North America.

Europe is the political and cultural center of the western world. From the Kingdom of England in 1284 to the present, the national territory of Britain has been rooted in Europe. Hundreds of years of operation and historical precipitation have made the roots of Britain rooted in Europe. After feudal rule and constitutional monarchy, Britain began to move towards the capitalist system. With the historical process of European hegemony, Spain, an old colonial power, began to decline, and Britain began to master seamount hegemony. 1763 defeated France and occupied Australia. Britain became the strongest country in the world and began to colonize everywhere. At the peak of the British Empire, the land area was as high as 34 million square kilometers.

At that time, Britain had a perfect social system and basic service facilities. Most colonies existed as plundering resources and did not invest too much in infrastructure. Compared with the prosperity of Europe, other British colonies are downright wild places. 1620, Mayflower arrived in North America and began the British colonial journey in North America. 1776, the United States was founded. During this hundred years, the United States has developed rapidly, but there is still a huge gap with Europe. The British look down on the early United States and will not immigrate to North America as a whole.

In the process of British colonization, the elite rarely left Britain. Only criminals, bankrupt businessmen, bankrupt farmers and political losers are forced to leave Britain to explore unknown wilderness. The early colonists faced great risks and numerous casualties, and the elites were unwilling to take risks for this benefit. Only after World War I and World War II did the United States become a superpower, and its domestic economic level surpassed that of Europe. It has been in a relatively backward state before.

Let me start with the overall migration of some countries. No country will give up its homeland when it is strong. As the folks say, the poor move and the rich move to their graves. Britain, which has become the world's number one power, will never move as a whole, let alone to the United States, which is not as good as Europe.
