Capitalism and market forces are very powerful in producing wealth and innovation. But we need to ensure that these forces act in the common interest.

I think if you look back through time, the history of income, wealth and taxation is full of surprise. So I am not terribly impressed by those who know in advance what will or will not happen.

Having a decent share of the national wealth for the middle class is not bad for growth. It is actually useful both for equity and efficiency reasons.

One way to have broader access to wealth is to reduce the tax on the large group and increase the tax on the very top so concentration of wealth doesn't get to extreme levels.
