>>3Great Replacement is actually a good idea and not a conspiracy: modern westerners are degrading in quality and have low birthrates in general, so there is the need to replace them with higher incentive people.
It is obvious, that immigrants (by the definition of being an immigrant) are very high incentive persons, who will improve western economy. The only problem with that approach is that countries originating immigration are losing their best members, meaning they will fall even further behind the West.
