Oh, you understand very well the implications of all this. Everything that you touch in your reflection is a strong part of the Venezuelan life nowadays.
We live normally in a flow between the legal and the black market. The government has tried to prevent it, but it can't.
In fact, the very cause of the black market is the prohibition itself. Economy has its own organic processes: if you push one side, it comes up from the other. The totalitarian governments are not capable to understand that, and they become everyday more violent against the people that simply try to solve their needs.
