EXELLENT IDEAS!
The fact that people go to places where they fellow countrymen are settled is true.
*But what happen with assimilattion? If some Italian go to Buenos Aires, argentina and then they became Platinean, they won´t attract anymore? I think place and assimilattion should be a major factor to inmigrants, like that Italian converted to platinean keep a ¨Italian ancestry¨ that attracts italians there, this ¨ancestry¨ still apllies to countries with major inmigration waves, like USA, ARG, BRA, AUS(tralia).
In Argentina Turk people (really most armenians and sirian-libaneses) went to Cuyo region because that place where like they homeplace and already turkish community was settled.(as an example)
* Economic migration must be reworked, not just because a product like iron is more expensive than wheat or cattle people will go there, why?
- Working in a mine was´t really good for almost all XIX century
- Most mines belonged to landowners or corporations, giving little money to they workers.
- Many farmers migrate, they knew and preffer farming.
Also OWNERSHIP or CONTRACTS about the land farming and such (for RGO) is a major factor for inmigrants to go. A farmer will preffer to migrate to a good land with good wather where he can own or rent a land rather than to work for a landowner.
-Also liberties of all kinds and democracy should give a bonus.
-Infraestructure should give a small bonus
-Life rating a lot more.
