@HemdadArwandi So why are the Persians and Kurds being persecuted in Iran, even though they are two brotherly nations? There are far too many executions. Is it because of the Azeris in power? Or is it because they are Sunni? Kurdish and Persian belong to the same language family.
It wasn’t.
With rare exception, colonies were unprofitable, meaning more was spent building infrastructure like roads, railways, buildings, etc. than was exported.
And look at places like Singapore and Hong Kong. Both were colonies for a long time and yet they are extremely prosperous.
