Pretty slick trick for the State, eh?
You know, get people all hooked on special favors by taking money from other people. Then, people in foreign lands want to get in on those favors and it attracts them. Then, the people whose money was being stolen want MORE government to keep those other people out.
If that doesn't work well enough, let's make certain plants illegal that people want. Then, we'll fight with guns anyone who tries to bring those plants over the border. When crimes increase and things start to crumble, the people whose rights to those plants were being infringed, want MORE government to build higher walls and use more violence and tougher restrictions to prevent the chaos.
Damn, it feels good to be a statist. It's so easy.
Government causes problems -> people want MORE government to solve them!
