The cost of discrimination

Tax day is a good time for a reminder about the "Gay Tax".  The NY Times estimated the life-time cost of discriminatory laws to a typical white-color gay couple:

We gave our couple an income of $140,000, which is about the average income in those three states for unmarried same-sex partners who are college-educated, 30 to 40 years old and raising children under the age of 18.  Here is what we came up with. In our worst case, the couple’s lifetime cost of being gay was $467,562. But the number fell to $41,196 in the best case for a couple with significantly better health insurance, plus lower taxes and other costs.
