Who really is tight?

Jews are supposed to be tight (Apology to any Jews on my contact list. I am not anti-semitic in any way, shape or form). Scotsmen are supposed to be tight and Yorkshiremen are supposed to be tight. Often Scottish or Yorkshire people themselves use this justification for being stingy. I find all three suppositions to be bullshit. How would a Scottish Jew living in Yorkshire fare if they were to be true? Would they fit ear trumpets to the side of their house so they can hear a penny being dropped in the street?
