Simple truth:
If you make $5,000,000 salary a year and your spouse make $80,000 salary a year, assuming you get a raise of $10,000 (small percentage for you, right?) and your wife also get a raise of $10,000 (big raise and hard to get), do you know who would take home more?
That is YOU, not your wife! She had to pay about $1500 more Tax (Fed + Socoal Security Tax) than you (rich and lucky guy) does. That is the so called fair tax code!
Do not tell me that you would get SST back when you retire, you will NOT! When a person who makes $10,000 a year would get more than he paid back, a person who make $80,000 a year would not. SST is a wellfare tax for middle class to support poor people when rich people do NOT make contributions.
