Yes the Fair Tax will collect the same if not more revenue for the government but it will remove playing favorites which is what the poster you replied to was insinuating I believe.
In other words it doesn't matter how many dollars flow into the government, what matters is how that money flow is channeled and who controls the channel gates. Tax law is what controls the gates and every legislator has their hands in crafting more tax laws. In short, that is what elected office boils down to, how many tax gates can be influenced.
If the Fair Tax Reform was passed, Congress would have to succumb to a budget rather than cut deals on tax breaks.
I believe the Fair Tax will pass in 2019, just about the time when the dire consequences of demographics force an overthrow of the present system.
Unfortunately Americans wait until they suffer a 'Pearl Harbor' before they resolve to fix their messes, and even then, as in 9/11, resolve may be weakened over time. And we will wait until the present system crashes before reforming anything. The coming changes in demographics will spur the tax revolution.
2019.
The only hope for a sooner development is some sort of Fair Tax zone experiment, where all residents and resident businesses (with strict definition of residence) of certain geographic zones (because most people are geographic based) would be treated under a Fair Tax system.
It's mainly a matter of how steadily the grassroots support continues to build ... and it is continuing to build.
We're now up to 59 backers in the House version - AND GROWING.
