Market economies are as old as human history. Economies centrally planned under the banner of socialism were an aberration of the 20th century. Of the 200 or so nations in the world, the number that now have centrally planned economies can be counted on the fingers of one hand. How out of touch with reality does a person have to be to believe that Barack Obama wants to centrally plan the U.S. economy?
Just as market economies are as old as human history, so is taxation, a sine qua non of a mixed economy. The highest marginal income tax rate this country ever had was 94% during the Second World War <link> . We can agree that that rate was confiscatory but the entire cost of wars shouldn't be passed on to future generations (e.g., the Iraq War). Today's taxation rates buy us:
public education
public streets and highways
public waterways and harbors
public police and fire departments
public retirement income
public health care for the poor and elderly
public parks and recreation areas
public libraries
public scientific and engineering research
public space programs
Free market ideologues like the late Milton Friedman would have us believe that all of these public services can and should be privatized in pursuit of the holy grail of economic "efficiency". Fine. Let these tunnel-visioned ideologues make their case. But I, for one, am going to ask that they do so without hysterical references to mass murder.
