“Your equity will be halved but so will your mortgage because we oblige the banks to sell off half of it to the government, and we then forgive it.”

“Your equity will be halved but your kids will be able to raise your grandkids within a 20 minute drive from you.”

“Your equity will be halved but you won’t need to worry about your retirement because of our new old age quality of life program.”

Very much this. This is how you do it. You give something material to people instead of relying on their idealism. Then they vote for the right thing.
