Seriously, modern society would cause evolution to move backwards, and that's because physical development would not be an advantage anymore.
Beat that!
You need to understand what you are talking about before you make too many wild statements.
Evolution doesn't have a direction so it doesn't have a forward and backward. It could be that the enviroment selects for bigger and stronger at one time and smaller at another. It is all just what best suits the environment of the time.
Humans, in some societies, may not be subject to the same selective pressures as wild humans were. However, that does not mean that we are not subject to any selective pressures.
For example, humans decended from Europeans who went through the black death have different genetic features than others. This is an environmental selection that has made a change in the genetic makeup of a population.
We are still evolving. We just don't know in what way.
