> Do you see many colonizers in present? I don't.
The main example of "old school" colonization (other than the Chinese example mentioned below) I can think of in 2016 is the Israeli colonization of the occupied territories.
Colonies provided wealth and a logistical advantage to their owners. UK and France both fought hard to hold onto theirs well past the end of WWII. More recently, Russia considered Crimea important enough to accept the economic punishment annexing it entailed.
> Chinese flock to Southern coast and no longer push that hard demographically on Uighurs/Tibetans.
Do you have a good source or book that I can read about this? I would like to know more.
> Germans don't even seem to flock to their Northern, Baltic shore. And it has better climate than absolute most of their supposed "scram".
The Nazis are not known for paying careful attention to the climate when drawing up their grand plans. Lebensraum was their official policy, and I doubt they would have left the local population alone, considering what they did to other undesirables.
