The thing is what do you do about people that refuse to accept colonisation? Even if you are right and people vote to be colonized, you have to kill or imprison the millions who resist. And even if that wasn't the case and they somehow prosper in a few decades, why would they not want independence then? Even texas wants to secede from america and the whole south fought a war. Either way, you will have a lot of bloodshed.
Also, this means a lot more of the people you colonize will immigrate to the homeland as you can see in Europe, can your people handle that give the birth rate difference and cultural incompatibility and all the "purity" xenophobes? Business is business. In case you don't know, majority of black people in the UK immigrated in colonial mid-20th century to work in child care,NHS,etc...from the carribean and africa (which is great) because local talent was short and expensive. The same will happen in any new colony.
It is best to be friendly trade partners and allies than master and slave. There are those who want peace and profit and there are those who are filled with violence and greed.
