You [Obama] favor eliminating the cap on earnings subject to the 12.4 percent Social Security tax, which now covers only the first $102,000. A Chicago police officer married to a Chicago public-school teacher, each with 20 years on the job, have a household income of $147,501, so you would take another $5,642 from them. Are they undertaxed? Are they rich?Doesn't George know that social security is not paid jointly?
