- we can see the futureLet's face it, nobody can see into the future, so whatever happens is unknowable to all of us, we are all just speculating as to what we think may happen. Why don't we all just wait and see.
- we know what happened in the past
- we can draw conclusions based on experience and facts
So prevision more than speculation and no need to wait and see who will suffer the most - the poor.
