Two days ago I noticed, that every country, where the white man doesn't live is called a "developing country", but in those "undeveloped countries" there is still a strong culture, which I think get's destroyed by the oh so wise white man.

You can only be poor in comparison.

The white man comes into the remote "wild" states, destroys the culture with drugs and weapons, with money and with an oh so civilized and "right" religion. All of the states' old wise culture and knowledge is lost.
The higher society moves in, enjoys life and exploits the natives.

And then they ironically send ads on European/North American TV, in which they ask for donations.

Unfortunately the damage can't be undone, so it would not even help if they FUCK OFF.
