I would have laughed at the sarcasm that you used in the post, had the situation not been so real.
They tax an income that is already earned through means that were taxed before hand. Which in turn were taxed previously. Tax till 'nothing' much less 'nothing taxable' is left.
I was looking at the debt-age demographics and it was a crushing realization. Most of the people born are to parents who are in debt. This child will incur some or other form of debt even before he reaches adulthood. As his parents pay of their debts, this child would grow socioeconomically and start incurring more debt. So as his parents debt decreases, his own would increase. The same cycle would follow in the next generation.
Born in debt - raised in debt - die in debt. I think this says it all.
