Nobody has ever liked paying taxes, but individual grumbling is growing to a loud chorus of complaints. The system of federal income taxes has become so complex that few individuals can compute for themselves what they owe and both personal and corporate financial decisions are often based more on their tax consequences than on their soundness from either a production or consumption point of view. All this leads to a perceived unfairness, with some better able than others to take advantage of preferences and loopholes in the system.
