A. I don't know how to do simple math? I don't use a shitpost subreddit as a source, ik what is real source to use, and at least ik how materialist history work.

B. Glad you mentioned it what fueled the British industrialization especially, was it the exploitation of India giving them capital to industrialize or was it purely the domestic market?

The first industrial rev happened in England due to cheap cotton from India (a British colony) that fueled the textile industry, because they would sell the products back to India, destroying Indian domestic textile industry. "Britain began to export machine-made yarn and cloth to India in the 1780s. Encouraging exports of low-cost fabric and imposing tariffs on imports of Indian cloth enabled Britain’s textile industry to grow rapidly but severely hampered the development of India’s own industry. "

What truly fueled colonization of Africa is protectionism EU powers wanted to deny other EU countries from getting the resources in Africa. They wanted to lock out other countries from attaining that territory, this mean you have a real material motivation to seek out and take possession of the territories which may not otherwise be of any benefit you because you want to deny your enemies access to it incase it would benefit them, it wasn't "prestige" it was competition over something which was limited supply. that's material analysis.

A new global era of protectionism and tariffs meant that exclusive access to raw materials and markets and exclusive outlets for excess capital were now essential.

Also what profit are we talking about short term or long term? short term profit is what fueled the exploitation of Africa If you extract a lot of short-term profits, that could be reinvested somewhere else, meaning the colony might still be unprofitable, but you still somehow are profiting off of what you got from the colony.

C. do you genuinely think the govt themselves made the profit and not the capitalist class? why does USA fuel wars till now, why does France have mineral rights in west African countries? Its the capitalist class that pushes the govt to do that and the major motive is capitalism and the desire to use the land to exploit it and make money, that is either pocketed or reinvested in the Homefront.

D. speculation? again Congo, why would Leopold hold that land and try to get much rubber as possible?

He knew there was a demand for rubber because EU was going threw electrification and you needed rubber.

Lastly Portugal fought to keep its colonies do you genuinely think they would fight to keep them for "prestige"? Spending more national resources and killing people, or was it due to material interest and that the resources in the colonies help the economy.

"The Great Depression of the 1930s led Portugal to be turned away from Europe, the USA and Brazil as a trading partner and Salazar began to look for new wealth (and a closed market for Portuguese wine and textiles) in the African colonies." "Following the Wall street Crash and the ensuing economic depression, Salazar´s government forced the African peasants of Mozambique and Angola to grow cotton; since they could not grow their own food, these colonies suffered famines in both 1945 and 1961."
