Two wrongs don't make a right

This maxim was cited by Edwina Currie, a former government minister, on TV (Channel 5) recently, regarding tax evasion as compared to benefit fraud.

The maxim is worth repeating; it illuminates, but it does not take into account the scale of the wrongs. Tax evasion and benefit fraud are both wrong, but the former amounts to far more £ than the latter.

This comment was provoked by a discussion of the current strike by TfL employees. Maybe TfL employees, especially train drivers, are not the most pressing cause in the drive for equality, but if banks are too big to fail and have t be bailed out, why exactly can't TfL (staff) be) bailed out?

Sorry for getting all "political" but the double standards are a bit too much.
