OP, you are delusional. I have no idea where you got any of these ideas from, but they can be separated into two categories.
1. Things almost all colonized peoples already had prior to any contact with Europe.
>roads (How do you think people engaged in trade, you fucking retard?)
>boats
>advanced agricultural techniques
>the idea of a writing system
>the idea of keeping track of their own history
2. Things that diffused throughout the world in this period, regardless of colonialism, and were more widespread in countries that were not colonized, e.g. Japan.
>modern house building
>modern medicine
>western ideas of democracy, republicanism, etc (This is not necessarily a good thing.)
>modern tools
>dams
>electricity
If you bother to look at statistical data on any colonized country, you'll find that the native population typically did not enjoy the benefits of boats, "modern house building," "modern medicine," or "modern tools," but were instead deeply impoverished, as in the case of the Indian peasantry and made captives of the European market. You will be hard-pressed to find a country that had anything approaching a positive experience with colonialism. The vast majority are poor to this very day, with the only exceptions I can think of being Taiwan and Korea, neither of which were colonized by your beloved white race.
