Tough one considering there's drawbacks to each one.
The past wasn't all that great, and it was better or worse depending on area. We certainly didn't have as many social benefits back then as we do now, nor the tech - but I have to imagine things were a lot more simple back then. Social interactions and norms had to have been different as well (and not for the better).
I would like to think the future has better things in store, but looking at just how this year went, I would not be surprised if we traveled a few years into the future and the entire place is just on fire. Scary to think about what'll come when just this year had so much going on.
