I didn't make the original assertion that a 17% increase in prices would be a wash with paying taxes on retirement withdrawals, I am disputing the assertion of the 'bender.

Under the current system the "qualified" money will be taxed at the taxpayers ordinary income tax rate when it is taken out, the real estate will be taxed at the capital gains rate as will the direct company stock.
Only the money set aside after tax will be tax free when put to use in retirement.
I can tell you from direct experience with hundreds of clients that most retirement "funds" are in qualified plans and will enjoy a boon under the fair tax. So will real estate and so will direct ownership of stock.
