The Federal government spends $12,000 per person. If you are married and have 2 kids and 2 retired parents, you will need to generate $72,000 a year in taxes. Half of the country doesn't pay any income taxes, so you will need to pay theirs, too. That makes the gross bill $144,000. The government gets about 42% of its revenue from income taxes, so you will be liable for $60,480 in income taxes. To get to that level, you will need to declare $270,000 a year in income.
If you earn anything less than that, you're not paying your fair share.
If I were you, I'd get to work.
