Why Do Tories Have A Hard-On For Low Inheritance Tax?

Low inheritance tax - conservative voters love it. But why? I mean, isn't it pretty inconsistent with the conservative ethos? Let's face it, Daily Mail readers- THERE IS GOING TO HAVE TO BE SOME TAXES. Get over it. And inheritance tax is a logical place to put tax if you're of the Tory persuasion. Why? Because conservatives are always bitching about welfare, evil evil people who scrounge of welfare and are lazy buggers. "Get a job, yer Polish wanker!" they cry. But is scrounging off your parents' inheritance really that different from scrounging on welfare? Yes, I know you don't cost the taxpayer directly if you do it, but the ethos is pretty much the same. Particularly if you want "Brits to be able to keep their hard-earned money" you can jack up inheritance tax and then cut income tax instead, which actually allows Brits to keep their own hard-earned money rather than some wealthy guy keeping his parents'.
So there you have it.
