I have an issue with anecdotal evidence even if it supports my POV! For one simple reason its very often false! In your example you have no idea by your own admission how the holiday is funded. There could be any number of perfectly reasonable explanations for that why pick the one that says "Scam"?

A universal income would be paid to everybody, so if one works, it enhances ones lifestyle always presuming that a person wishes to have the rewards that a paying job provides.

I don't understand why people are so keen to "punch down" on those they feel are gaming the system, yet ignore the far bigger financial and other scams that are happening elsewhere. Given that tax evasion and avoidance is costing the Uk more, I'm more irritated by people who earn millions paying an effective tax rate around half of what I pay then somebody scraping around at the bottom.

Having worked with lower income groups, there is no way I'd want their lifestyle and I doubt many of the people moaning about it would either.

I mentioned the CEO's et all, precisely to make the point, there is a tendency to "punch down" and in doing so overlook the real scammers and people playing the system. I suspect that's because many people don't think avoiding tax, not paying full wages or getting an unfair advantage through connections or private education is exactly what they would do if they had the chance.
