Neo colonialism can save the world

During the days of western colonialism, things were cheap. Cheap labour, cheap land, and low tariffs or no tariffs. The British came and just take over Africa, India and Malaya, including Singapore and many Indonesian islands. And they plant rubber trees on them, mining tin etc. No land cost to talk about. Then they imported indenture labour cheaply from India and China. No need to pay for work permits, maid licence, levies etc. And their import and export to their colonies around the world, tax free also, or very low taxes. A world economic systems built under the same principles of the colonialists must be a god sent solution to the worlds problems. There will be no inflation as all the costs of production will be very low. Instead of planting rubber trees on colonised land, they can opt for palm plantations. But better still, build high rise and high end residences for the rich. And they can sell them cheaper if they want to, as the land is free. Or they can maintain market prices and reap in obscene profits. And some land or sea are rich in oil. And labour must also be must cheaper as colonised people cannot bargain nor have they any rights or be protected by labour law. The wages can be suppressed and kept very low. Looking at all the advantageous of colonialism, it looks very attractive for the 21st century!
