That’s the bureaucrat-unionista solution for all our fiscal problems. Like most populist solutions, it’s short, simple, and wrong! In other words, it’s a perfect fit for the Liberal-Regressive psyche (see The Progressive Übermensch for a discussion of the Regressive mindset). Typical of Liberalism, it is based on false assumptions (or outright lies)–primarily that the rich aren’t being taxed and that they have enough money to pay all our bills.
The standard conservative response is to point out that we already do tax the rich. Whether that response is correct depends in large part on how you define “the rich.” As is usually the case with liberal-regressives, they don’t even know what they mean by the term. “Tax” is usually a reference to the income tax, individual or corporate. “Rich” is ambiguous at best. Since they’re talking about income taxes, it is natural to assume that “rich” means “high-income.” However, when they talk about the rich, they seem to be referring to people who don’t “work” (a Marxist term based on lies) at all; they merely take and sit around counting their wealth.
