It's hard enough to argue with you, I'm not adding an unnamed 3rd party to this conversation, if you think X Tax is a good idea, say so and be ready to defend it.
I don't have to defend it, I'm merely giving you options other than straight income taxes. You seem to have tunnel vision right now.
Again, I don't accept that the US have a household saving problem right now, but again, this is a REALLY bad way to approach that issue.
You want to more people to save, you raise interest rates.
This is not how it works. You don't raise interest rates to cause savings (in fact, gov't bonds, which is saving, are at an all time low and yet people demand them like crazy), interest rates rise as banks demand more savings. You have the process backwards. rates don't cause savings, savings determines the rates. It's like prices. You're essentially arguing prices determine demand (interest rates are the price of money).
It's why the austerity hawks have gotten the whole interest rate prediction stuff wrong. A rise in interest rates right now would be because the economy is better and there's more disposable income and thus banks want more money and are willing to pay more for it, not because a lack of bond confidence (which is akin to your deflation worry).
And before you say "The Fed controls rates," this is not accurate. In controls the Fed Funds rate and it ties to influence the general interest rate. But the market can ignore it. Your options at the banks, for example, are not low because of the Fed. They'd be low regardless because banks do not want your money much right now. A couple years ago, they sort of wanted to close up shot and take no one's money.
People are not saving not because there's no VAT (don't make pull up data on household saving differences between states, please), they're not saving because there really aren't any good saving avenues for the common working family, and because many of them literally don't have any disposable income.
I just argued this! If you think my argument is people don't save because there is no VAT, you need to go back and re-read because that is a straw man.
There is a huge retirement problem, but in its root is the terrible 401k model, I don't know how much more you think VAT going to make people put in their retirement funds, but it's not going to be enough to make a dent.
Separate issue, but if you think the US undersaving didn't make a dent in the Great Recession, you're very very wrong. It was an balance sheet recession for a reason and exactly why it has been much harder to get out from under.
I reject their methodology pretty much completley (and I resent you for making me read it).
Also, I'm not sure how exactly you want to apply that paper to the discussion we're having.
p.s.
I thought about it a bit more and I think your complexity argument is bunk.
Let's say we want to change our tax code so that 60% of the population don't have to pay taxes, still, you need to answer why it is better to replace that revenue with VAT rather than raising income rates on the rest of the population (but again, I think your 60% number is unrealistic).
I don't know what to say. You're entire argument seems to be "I just don't agree and I don't accept any argument to the contrary."
basically: You: Can someone explain what benefits a sales tax has over income tax?
Me: Here are the benefits
You: Nah, I think that's wrong
Me: explanation why it isn't
You: Not buying it
I mean, I don't know how else to approach it. I don't know of many, if at all, economists from any school of thought that thinks an income tax is no different than a sales tax from an aggregate economy point of view. And any data I've seen agrees with that. You seem to reject any notion to the contrary. When I ask you, through questions, to think of things in a different light, you ignore the questions.
I think we're at an impasse.
