    When Obama was running for president, I remember that he wanted to remove the cap on Social Security tax and also wanted to increase the highest income tax rate to 40%. That means that as a self employed business person in California, I would be paying 40% (IRS) + 10.55% (CA) + 15% (SS) = 65.55% of my income for state and federal taxes! How is it that a person can think this is right? I guess this is the definition of socialism. I am allowed to keep one-third, the government takes two-thirds.
