The great justice of a consumption tax is that no one can use any loopholes that others don't have to avoid taxes, everyone (rich, poor, foreigners, criminals) pays the same tax whenever they buy anything.
This type of tax would at least gain tax revenue from the criminal class who pay no taxes on the fruits of crime.
One added benefit of a comsumption tax is that the government could no longer user the IRS and the tax forms to gather data on us and how we live our lives.
The rationale for taxes on business escapes me since businesses don't really pay taxes anyway... their customers pay higher prices for goods and services, stockholders get smaller dividends and smaller earnings per share and labor pays with fewer jobs and lower wages and benefits, all the result of business taxes.
That's not to mention the armies of lawyers and lobbyists that business must employ to fight the assault of government and politicians on business activity... the tax code for business almost acts a protection racket run by politicians and lawyers to create a job market for tax lawyers and lobbyists.
If the tax on business didn't exist, think of all the resources presently being spent by business just to hide income from the government and to buy the goodwill and influence of politicians.
