What was different between North American and South American Civilizations, and what factors allowed for this

im not sure on this one

informed opinion on immigration policy and immigration reforms from the american pubic is not complicated but a nuance. most americans support secure borders and they are not happy that the national’s immigration system is broken. people think that immigrants that shoulder similar responsibilities like native americans should be able to become americans. in the recent polls, stats have shown that there is a good support for tenets of comprehensive immigration reform. for example, in recent polls concerning opinions on immigration reforms, voters want congress to act even if status quo has no support. immigration opponents suggest that latino and non-latino voters disagree and there is controversy in the issue of citizenship.the truth is that the issue is about its leadership and problem-solving aspect and not about immigration reform.the opponents of immigration reforms advocate for the promotion of two myths where the first one is that republican politicians have a choose on latino votes and the second one is that the path to citizenship for unrecorded immigrant is controversial among all this !
