The swifter the changes, the greater the costs. It's well known. The fact that it is a post-crisis situation modifies this seriously though.
But like I said, in a post-crisis situation people are ready to alot more for things to get back to normal. Post-1929 rulers were bringing swift changes and the majority could be very very happy even if some were left behind (especially in Europe with fascism). People are already unrooted partially, so there is less to shock and unroot.
Anyway, lots of people lose their jobs and/or needs to relocate, the infrastructure adapts and moves too (partially), so as the economy or the approval ratings.
thx, and hope it can help
PS: But as I said, just some effect on approval ratings would suffice.
