I think one of the biggest concerns that governments are having is that the more you try to re-balance wage stagnation and wealth, the less competitive you are in the world, leading to other types of stagnation.
Yet the period 1946-1973 saw enormous growth in all western countries and wages kept up with growth during that time.
Of course, it seems likely there are government interventions that damage growth. But apparently there are some that don't. In particular, progressive tax structures and social safety nets don't seem to.
