What he misses out on completely is that "trickle down" has the effect of improving everyone's lot in life to varying degrees, it has never laid claim to be a means of equally sharing wealth.

Neither the author nor I ever suggested it did. It does however ensure that at least some of the wealth is being spent by people who need it. Unlike some others on here I do believe that capitalism can work and provided that there is a good measure of social responsibility it is not a bad thing. As I have pointed out before a good economy relies on capital, labour and natural resource to work properly. Concentrating on one to the exclusion of others will never work properly.
