Please see my poll at the ‘moral theology’ forum. It may be misplaced, might be better under ‘Social Justice’.
Also, our tax system is already very very progressive… i.e. top heavy… I think that’s why those against further 'redistribution" via taxes have a legitimate argument. However, we do have a serious income distribution issue. There needs to be a better understanding of the root cause because “taxes” don’t appear to be the solution. We also have to be “competitive” with our taxes (and other things) since we do deal in a global economy, like it or not.
One not so savory hypothesis is that historically a small middle class is normal. (A necessary buffer between the haves and have nots) The haves and the have nots (mostly have nots) make up the majority. Market forces determine this and those forces, especially on a global playing field are bigger than any US policy. It is a conundrum, for sure. What we really need is for the quality of life for the entire world to be raised. Make them all good little consumers like we are, buying refrigerators, washers and driers, even having electricity and running water. Maybe they can all have the opportunity to become obese too. Wouldn’t that be something. But alas, we can’t make their governments “do the right things” any more than we can get our too (okay that was a little harsh). People have to “choose” to do the right things, not be coerced by their governments. That requires, education (especially the virtues and deadly sins), evangelization and enlightenment. It will be done, sooner or later.
