The main arguement put forth by advocates of the singlr tax movement was that:
a. Taxing only income would make for a more equal society.
b. Taxing only land would be very efficient because taxing land does not increase its supply.
c. Taxing only imports would help protect local jobs and stimulate local entreprenuers.
d. Having only one tax would be much easier for people to understand and much less costly to administer than our current system.
