Yes, my post was flippant.
I think, however, it is important zoom out every so often and look at the whole historical scope of human existence. In any particular generation there is disparity among society members. But if we look at the overall standard of living and well-being of societies, say in 100 year increments, there is continual improvement.
Modern market based economies are what seem to work the best to date. Market economies recognize the instinctual need for incentive and reward in the human condition. I think less attention needs to be paid to income disparity and more towards a better minimum standard of living. Having ones health, a climate controlled roof over ones head, balance between required work and leisure, is all one needs for an enjoyable life. All the rest is superfluous.
The next step in market economies however, is to include the full cost of activity into the cost of product and services. That all costs, including product end-of-life reuse and recycling should be included in the cost of the product. Environmental costs should factor into all market endeavors to achieve a low or no-impact economy on the environment.
Markets work as long as we continually work to improve them.
