Of course, changing the mind of a non-dillusional person is already hard enough.
The creation of jobs is everything. If your life stops being a competition for survival, people outside your social ingroup stop being existential threats.
You told them or you explained and developed a plan? This is all hypothetical, because immigration also creates jobs, but to somebody threatened with losing their job, it doesn’t help that they know that the king is to be blamed.
My assumption is that they believe that a unified society can change the decisions of the king. How do you convince them that the immigrants are on their side?
BTW, it doesn’t matter that the king has the majority of surplus. The problem is that he doesn’t use it to employ everybody.
How can the left not link immigration with the reserve army of labor?
The right thinks that limiting immigration removes the surplus. The left knows that there will always be a surplus but they attack the right on refusing immigration instead of first explaining the reason for the surplus.
To stay obvious, what’s fascinating is that those networks are small, its members the most intelligent people available and they meet each other regularly in person at conferences.
