Readers in the States can substitute Democrats, Germans can use Social Democrats, etc etc -- they're all singing from the same crackpot theory Robin Hood song sheet, where the strapline is "we'll rob the rich to give to you the voting poor majority" but the footnotes say in very small writing on the back page, long after you will have got bored and stopped reading, "not really, we are the rich and do you really think when you add all this up we will have given you diddly-squat? Suckers."
