What is the main reason for the rapid growth of world colonies from 15 to 16? (Please answer briefly)

The most rapid development is the British North American colony, which is now the powerful United States. In addition to owning a lot of fertile land like the Spanish and Portuguese colonies, they also enjoy freedom and equality to a greater extent. Although their foreign trade is also subject to certain restrictions, they enjoy complete freedom in handling their own internal affairs. The prevailing political system is conducive to the transfer and division of property. If the landlord's land is not cultivated within a limited period of time, [the official] declares that it can be owned by anyone else. In Pennsylvania, there is no right to inherit the eldest son, and in some States in New England, the eldest son can only get two copies of the property. No state collects tithes, and hardly any taxes are levied. Because the price of fertile land is extremely low, it is most beneficial to use capital for agriculture. Agriculture can provide a large number of most valuable products to the society while providing the largest number of jobs that are beneficial to health.

As a result of the combination of these favorable conditions, the population has increased at an unprecedented speed. It is seen that the population of all North American colonies has doubled in 25 years. In 1643, the number of people who originally settled in the four States of New England was 21,. After that, it is said that more people left there than went there. In 176, the population there increased to 5 thousand. Therefore, the population there has been doubling every 25 years. In New Jersey, the population doubles every 22 years; And in Rhode Island, not even 22 years. In the belly colony, because the residents are devoted to agriculture and don't know luxury, their population doubles every 15 years, which is a very unusual case of population growth. Only in the coastal areas where people naturally live first, the time to double the population is about 35 years; The population of some coastal cities is completely stagnant.

These facts seem to show that the population is increasing in proportion to the removal of poverty and sin, which are two major obstacles to its growth, and that the most correct criterion for measuring people's happiness and innocence is the speed of population growth. The unsanitary city (where some people are bound to be driven because of the nature of their jobs) should be regarded as a kind of poverty, and all kinds of minor obstacles to marriage due to people's expectation that it will be difficult to support their families in the future can also belong to this category. In a word, it is hard to imagine any kind of obstacle to population growth that cannot be attributed to poverty or evil.

The pre-war population of 13 American states is estimated to be about 3 million. A few immigrants from Great Britain have made the population there so fertile, but no one feels that the population of Great Britain is decreasing now. On the contrary, as we all know, a certain degree of immigration can also promote the population growth of the home country. It is particularly noted that two Spanish provinces have the largest number of immigrants to America, and as a result, the population of these two provinces has greatly increased. No matter what the original number of immigrants in Britain led to such a rapid increase in the population of North American colonies, we have to ask, why didn't the same number of immigrants in Great Britain increase the population in the same period? It can be said that the important and obvious reason is the lack of land and food, or in other words, poverty. Compared with evil, poverty is a much more powerful reason, which is fully manifested in the fact that even some ancient countries have quickly recovered from war wounds, plagues or natural disasters. At this time, these ancient countries are almost in the state of emerging countries for the time being, and the results are often unexpected. If the residents' diligence is not destroyed by fear or tyranny, the means of subsistence will soon exceed the needs of the reduced population, and the inevitable result is that the population, which used to be almost fixed, may begin to increase immediately.
