I’m sure that in your line of work if you say something is going to happen you better achieve those results or suffer the consequences. This doesn’t occur in the world of politics where politicians promise that if their laws are enacted this great outcome will occur. When it doesn’t meet those parameters they will blame the opposition 1st, foreign government, the dog as long as they don’t have to take the blame.
I believe that every piece of legislation must have clear goals that must be achieved within a clear set date. If the legislation doesn’t achieve those goals by the set date it either needs to be reformed or revoked.
