I am currently researching for my point. Please be patient. - (EDIT) Ok. I found the website I was looking for.
Though I agree that the income tax is flawed, and it needs reformation, those that suggest we abolish it don't see the problems asosciated with such an act.
The biggest problem is that there is a huge industry based around income taxes (the accounting industry). Chicago sun times estimated that it was a 200 billion dollar industry. That would make it worth 10% of all the revenue of the government, and 2% of the US's GDP. That would be a huge thing to loose. Further, I haven't been able to find any stats, but I wouldn't rule it out that the marekt vaule of all the accounting corporations is more than 2 trillion dollars. They would sustain a cripling loss in value if they loose their income tax accounting income. This would hurt the 331,000 certified public accountants (American Institute of Certified Public Accountants), the public who own the stock in these companies and the economy as a whole.
I agree that there need to be some changed in the tax structure, and I am up to a discusion on whether lower tax rates actually increase tax revenues, but the point is that income tax is an essential and integral part of our society and our economy and ending it would be a massive problem.
Thanks for listening to my thoughts.
