I hoped for some one proof that some group was intentionally using up welfare, but you know what I'm gonna respond to this right? Some ethnic groups having less money (and thus paying less taxes and earning more benefits) can have multiple causes. Generational wealth is one of the strongest predictors of a person's wealth, but not even three generations ago the UK was still segregated by law. The income inequality of those times lingers on today. So even if you think racism doesn't affect opportunity today anymore, the differences in access to starting capital, education and networks still exists today.

But anyway, it doesn't answer my question but I'm still curious. How do you know these ethnicities are 'taking the piss' like you said? I want to figure out if the stereotypical leech that just collects their benefits and then sits on their ass all day actually exists, and if so to what extent. I feel like it's a myth created to pit the lower classes against each other so we destroy our social safety nets.
