@Jaxk Since you’re being reasonable, I’ll do what I can to reciprocate.
To start with, if housing costs are tax exempt, even if only on primary residences, then mansions cost the same as ghettos; there is either an exploitable loophole or complex codifying. And it would get more complex as that part would have to be adjusted regionally due to widely varying housing costs around the nation.
Next comes the fact that there are certain things that are neither housing nor food that people at all income levels use. I already have my buying power dropped almost 10% by living where I live compared to living in NH, which means I consume less. Those that make a living from production and distribution will feel a hit if you multiply that out by the population that is just getting by as is.
I don’t think a 15% increase in net income would help much either because, like many who wind up filing bankruptcy, that “extra income” would still not increase my discretionary income. It’s not like that 15% would be enough for people to do the things one would think would be possible with 15% more money, especially not if their purchasing power is reduced by higher prices. I see it as no real benefit to those that could use that 15% for something other than investments no matter how good it sounds; it may get the well-off enough to buy the V-12 Benz instead of the V-8, but it wouldn’t help the common folk that are the majority in this country.
That brings us to the matter of capital gains. If we didn’t institute some sort of luxury tax on spending without consumption, it would be regressive to the point of being repressive, but if we did the tax code would be so full of attempts to clarify what gets taxed as consumption and what gets taxed as luxury with just as many holes as there are now that it would be pretty much our current system only with tax brackets being determined by means other than AGI. I mean, those who work their asses off to make a business and sell it shouldn’t be penalized for that hard-earned windfall, but without a few thousand pages of Legalese, that would be the only way to tax those whose income is vastly greater than their consumption. Do you want something that’s just a repackaged version of what we already have? I don’t.
Now, if we were starting from a clean slate and institute Consumption Tax in concert with other MAJOR reforms then I could see it possibly working, but the fact that it would require a clean slate alone makes it non-viable without even getting into the other changes that would be required to make it work. And that assumes that we get it perfectly right, which I don’t see happening given how they’ve had plenty of time to make the current system work yet have failed to do so.
So, in short, I see it as so highly idealistic that it’s totally unfeasible. And sadly, we’ve let our current situation go on long enough that I think the best we can do is delay the inevitable and hope we can cushion the hard landing; no amount of reform can save us from the tides of history now.
