Just wait and see, in a few days, the US will loosen up the sanctions due to IR begging them to do it and the IR will get the opportunity to satisfy a few of peoples demands and everything will be fine again. US is just teaching their own servant a lesson as they did a few times in the last 40 years and the servant will obey while keeping face infront of their domestic followers.
They don't have to. I'm sure they will if there's a need, but there's no need. Everything is under control. A welfare state has its benefits. This is one of them: No uprising can ever succeed.
The economic fact is, Iranians have been living beyond their means. It's not possible to sustain 80 million people without foreign aid anymore. There is no foreign aid for Iran , so the standards of living need to come down. This is exactly what JCPOA (BARJAM) was about. I.R wanted foreign aid, hoping to be able to continue their plundering of resources while maintaining a somewhat respectable welfare state for the ever entitled nation. It didn't go as planned, because ...well...Trump. So now they have no choice but to give up on that "respectable" part.
Other than that, not much is going on.
