Finding remedies for inequality

On April 3 the T-R published an opinion piece entitled “The Myth of Inequality.” The author argued that “using inequality to justify social engineering or wealth redistribution is a proven formula for disaster.” What if social engineering has been used to create a system of taxation that is proportionally more burdensome on lower income earners than on the higher? Is there not a minimal income for survival? How is it determined and who would create a remedy? Would it not be rational to find remedies for extreme inequality that would benefit the financially comfortable as well as the very poor?
