How did Spain, Britain and France, once colonial powers, decline?

The early colonial powers used the wealth plundered from the colonies for pleasure, and capital wealth flowed into France, Britain and the Netherlands, which became the original capital accumulation of Britain and France.

Britain:

In the second stage, the colonial powers made full use of the colonies to plunder wealth, which was once called "the empire never falls". During the second industrial revolution, because British capitalists relied on their strong colonial rule, they were unwilling to replace new equipment and adopt new technologies, and their development was relatively slow. Colonies successively launched uprisings, Asian storms, Indian national uprisings, Afghan people's resistance to Britain, and the liberation of India. This makes Britain unable to cope. However, in America, they became independent.

I don't remember French. The information is as follows:

Since17th century, France has established a huge colonial empire in Africa and other places. However, as the country with the largest number of colonies in Africa, France bears a heavy burden of immigrants on the back of colonial retreat, with the exception of Tunisia in North Africa. 1? Except Morocco, sub-Saharan African countries not only have poor economic performance, but also remain in the tribal political stage, and wars often break out. In this two-way sequela, France's colonial policy? 1? The immigration policy is hard to blame.

France is located in a land with many powerful countries. If it wants to maintain its status as a big country, it must firmly implement the local strengthening policy, that is, the "mainland policy." In contrast, "overseas policy" is secondary and instrumental. Therefore, France's overseas colonization is largely used to strengthen local construction and strengthen local status as a big country.

Black Africa (sub-Saharan Africa) has long been exploited by colonists. When France had to quit, it tried its best to attack the colonies, ordered the transfer of all equipment that could be packed and transported, and destroyed most government files and even telephones? 1? The toilets were demolished and blown up. After this destructive independence, black Africa was influenced by history? 1? Religious and ethnic issues are entangled, civil wars continue, and the economic situation is deteriorating, especially in the current international competition.

Compared with black Africa, it is much more painful and difficult for France to abandon Algeria. Because France has extremely important strategic interests in Algeria. In France's huge colonial empire, only Algeria is called "France". "Algeria is France" is not only a slogan, but also an established policy. 1854165438+10 After the Arab War broke out in October, former Governor narayan said: "Without Algeria, we would lose the whole of Africa in a short time, and then the whole French Federation; It will also make France a second-rate power and even a vassal country. "

France's tolerant immigration policy has also caused many North African Muslims to immigrate to France, and now the total number exceeds 3 million. They brought fresh labor to France, but also brought many social problems. Immigrants have a low level of education and are at the bottom of society. The escalating riots in Paris are a violent rebound caused by the failure of immigrants to integrate well into society. How to deal with immigration in this year's French general election is an important topic for candidates of all factions.
