mike68, the companies and businesses employ the workers, the companies and businesses create the cash that goes to tax revenue.
Which bit of the above do you not understand?
No companies or businesses equals no tax.
If not for the companies and businesses there would be no income for the employees.
For you to think that it is only the individual tax payers who contribute to tax revenue is a major error on your part.
The individual tax payers only make up part of the contribution to the governments tax revenue. If you are still having difficulty in understanding that, I'm afraid I've done all I can and cannot help you anymore.
I do find it hard to believe that you really cannot see how income can be generated and taxes paid outside the scope of "individual tax payers".
