NO!! I swear, if you are going to work you should have a basic understanding of our tax structure.
We have a system of marginal tax rates, meaning you only pay the higher rate on income above the threshold. Simple hypothetical example: Say all income below $30,000 is taxed at 10%, income from $30,000 to $250,000 is taxed at 30%, and income above $250,000 is taxed at 40%. Today you make exactly $250,000. You pay taxes at the rate of -you guessed it- 10% on your first $30,000 and 30% on your income from 30K to 250K. Now tomorrow you get a one dollar raise, and make $250,001. You will pay the exact same taxes as yesterday, except now you will pay 40% on that $1 rather than 30%. So your taxes went up by 10 cents.
This assumes you have zero exemptions or deductions. It also assumes you aren't a CEO who is paid in stock options, and only pays the capital gains rate of 15%. It also assumes you turn off Fox News long enough to learn the tax code before you write the check.
Finally, just food for thought- in the 1950's, during the biggest boom ever, during a Republican administration, we had marginal tax rates in the 80% and 90% range for extremely high incomes. Lots of factors involved in why the economy was so good then, but just pointing out that current tax rates are pretty low in relative terms.
