This is the playbook (in Iran): you empower an enforcer class typically from otherwise marginalized communities, and give them a life that is very normal to the most of us but it’s what they could only dream of. I estimate that number in Iran to be around 2m-2.5m. Thanks to oil revenue they can keep these people happy for the foreseeable future. You have the loyalty of these people for sure.
There have been 3 popular uprisings in Iran in past 6 years. In November 2019 1500 people were killed in the streets in a week. I’m sure you’ve heard about the one after Mahsa Amini was murdered. None of these have led to any meaningful change, and at some point people consider the human cost in their calculations.
