Also absolutely workable. I'm not supporting it or saying it should be done but it is absolutely a workable solution to the existing problems.
As for increasing taxes. You cannot tax what does not exist. If simply raising the taxes would solve all such problems Venezuela could easily pull itself out of it's current crisis by doing so. You eventually reach a point of not just diminishing returns but where you begin to burn down the tiny bit of wealth you have. The poorer a place is, the sooner this happens.
