There's nothing wrong with trying to minimize your tax burden. Anyone who pays more than a cent than they owe in taxes is being a little silly. There's not necessarily anything wrong with advocating for tax reform, either, though the "I AM PAYING MORE THAN MY FAIR SHARE" crybaby stuff tends to highlight a blind spot to the bare-bones lives people who are "lucky enough" not to pay federal taxes (and sometimes state taxes, though this is less common) tend to lead.
But get a little freaking perspective. At the income level people are talking about in this thread as somehow not being middle class, you're making at least $40 an hour after taxes, even if you're in a high tax jurisdiction like Cal or NY. Even adjusting that for the higher housing costs in Cal or NY, you're north of $20-30 as-adjusted for higher COL, per hour, after state/federal income taxes, FICA, medicare. Don't cry about the reduction--you made the choice to live there. If you can't market your skills for the same income elsewhere, then that's really what you're worth; if you can market your skills for the same income elsewhere, then do it. Or accept your decision to effectively make less money to live where you want.
If you think that doesn't put you solidly in the upper class in this country, compared to the vast majority of people, you're out of your freaking mind. $20-30 hour COL-adjusted post-tax is more than the vast, vast majority of people make, it gives you opportunities to save that very, very few people have, and it dramatically shortens the retirement runway (from the 25-30 years/entire adult life most people have to the oh-my-goodness-world's-smallest-violin 8 years referenced in here).
Also, the idea that you're middle class because you work hard and want to provide for your family? Are you kidding? As someone said earlier in the thread, you can rename something if you'd like, I guess, but that doesn't make it so.
