After seeing your posts here for the last five years, I'm rather surprised to see you make such insupportable claims.
Just the opposite is true in both cases.
Our economy is shackled by the current monster we call the income tax code, and can only thrive when relieved of those chains.
And it is shocking that you can't see what an increase in personal freedom and privacy would result from this necessary change.
True to a point. The shackles come from the 'progressive' nature of the tax; it punishes productivity.
"And it is shocking that you can't see what an increase in personal freedom and privacy would result from this necessary change."
You've made an assumption that is not in evidence. If the tax includes services, it's effects will be grievous on independant providers of many services. I'm talking about doctors, lawyers, engineers, accountants, building contractors, music teachers, tutors, and likely pastors of churches. You have failed to apply what you already know about the nature of government, to the implementation of the tax.
Privacy will be non-existant for everyone, because government will be allowed to presume that all are possible providers of services. Your bank accounts will be scrutinized as never before. This is already going on in other countries, so you don't need to rely on guess work. The U.S. govt. will work on the same model as all the VAT tax countries are following.
