A Libertarian sales-tax party?

Is the Libertarian Party becoming a sales tax party?  The past several LP candidates for president have favored excise taxes.  I don’t recall any of them declaring, “Taxation is Theft!”  Now we have former New Mexico governor Gary Johnson as a leading candidate for the LP nomination for president, having abandoned the quest for the Republican Party nomination.  His tax plan as a Republican was a national sales tax, and that remains his tax plan as a Libertarian.

The main organization pushing for a national sales tax calls it a “Fair Tax.”  That is excellent propaganda, but a sales tax is no more fair or just than a tax on wages.  A sales tax violates free trade, makes products more expensive, and indirectly taxes wages and other incomes.  The advocates claim that a shift from income to sales taxes would not raise prices, since the income tax already raises prices, but they are wrong, because much of the burden of a tax on wages is on labor.  A sales tax has about the same excess burden or deadweight loss as an income tax.  Income taxes punish savings, but sales taxes punish borrowing, and there is no logical reason to favor savings over borrowing.  Savings and borrowing should be voluntary individual choices not skewed by taxes or subsidies.

The “Fair Tax” plan exempts business purchases, putting the burden on households.  That invites massive tax evasion, as folks would claim to be buying stuff for a business.  The response of government would be a sales tax gestapo.  If you did not have a receipt for your purchase and could not prove it was for business, you could go to prison.

If the Libertarian Party becomes a sales tax party, it will be unpopular and get little support.  Historically, sales tax advocacy has been a political loser.  This may well be why Gary Johnson got so little support as a Republican candidate for president.  If the LP nominates a sales taxer, I for one will promote the Free Earth Party (http://free-earth.foldvary.net/) as a truly libertarian alternative.

Austrian Economics and the Left

Matt Yglesias has a post up over at Slate.com on Ron Paul and Austrian Economics.  I won’t get into the details of what he got right and wrong about his largely honest attempt to explain the Austrian School to Leftists (the word “crank” was only used once!  A new high for the Left).  Instead, what I’d like to do is hone in on this whopper:

Many of the original Austrians found their business cycle ideas discredited by the Great Depression, in which the bust was clearly not self-correcting […]

Has Yglesias conveniently forgotten about Hoover’s attempts to prop up wages and his signing of the protectionist Smoot-Hawley tariff?

Why don’t Hoover’s policies get more attention by economists and journalists trying to understand and explain the Great Depression, or am I missing something?
