The whole “millions of immigrants” is just a property of the recent alt-right attempt at a take over of HN.
Looking around, it appears that immigration rates were raised due to aging population issues. While other places around the world are looking at moving retirement to 75.
Crony capitalism is causing higher immigration, so it’s somewhat hilarious for these people to think that an even more crony party is going to help offset this.
