Maybe it is you who should read more closely, and then think on what you've been reading? Capital gains are currently taxable at 15%, capital cost basis at 0% [already taxed] - and you would like to tax them both at 23%. My point was - exclusively - the double taxation, in this particular case of the capital cost basis.
Well, I think you're wrong - Man50D doesn't want to tax anything.
Beyond that, what specifically are you asserting that the nrst will double tax to an extent greater than now?
No Slob, your presentation makes no sense at all. Capital gains aren't taxed under the FairTax when they are earned. Only that portion spent - and spent for taxable things - is taxed and even then an individual's effective tax rate will not be 23% (no one will ever pay that effective rate) but much lower. Even spending at twice the poverty level results in a very nominal effective tax rate.
"Capital cost" (whatever you think that might mean) isn't taxed by the FairTax so that comment makes no sense at all. All income under the FairTax is untaxed until spent and even then the taxpayer has full control of his consumption in both amount and timing ... unlike the present tax system.
