Anything less than a flat rate tax... where everyone pays the same percentage... without any credits or deductions isn't going to be fair. So there is a lot of unfairness going around... problem is its unlikely to ever be fair.
Until it is... you hire a competent tax preparer who can find every deduction you are entitled to and give advice to you on how to maximize your next years deductions. As long as they exist.. there is nothing wrong with taking advantage of them. Someone else will be.
