Please do not paint the poor as feckless drunks, some may be , some rich people are be too, the only difference is wealth. Few single mums chose to be, most have been let down by a man, who pays at best minimum for the children. The father may be dead or disabled. If the mother has dodgy health, or a minimum wage job the child may well be being brought up in poverty.
We imported labour from many countries to do jobs we didn't want to do, while we were doing that our countrymen and women were going off to the antipodes or Canada, some have come back later or on retirement, I know a lot of nurses who did that, to live in a pleasanter climate while we got Irish or Carribbean nurses to do the job we'd trained them to do. Where would I be without doctors or nurses or dentists from overseas, dead probably. Thank heavens we have them. For many it is luck rather than hard work which has given them an easy life, a different decision at a crossroads in their life, a company they worked for closing down, s drunk driver disabling or killing a breadwinner, a freak accident if birth that means you have to give up your job to look after a child with a rare congenital issue...some are born to wealth and privilege, it's not their choice, others are born in poverty and to get to where the rich person is will be an uphill struggle. Wronguns are wronguns whatever their origin, but wring behaviour is brushed off if the person is from the wealthier strata of society, and often demonised or thought of as feckless and to blame if they are from the lower strata, or are incomers from elsewhere.
We'd be so much poorer as a society were it not for the efforts of immigrants over the centuries, Huguenots, in London, Germans in Bradford to mention just a couple of groups. Not all the wealthy are just take, take, some are philanthropic, and care about their neighbour who is struggling. Some are immigrants elsewhere, channel isles, Isle of Man, or other tax havens, avoiding paying the taxes that would benefit so many. They are every but as antisocial as those at the other end of the spectrum. And the likes of Prince Andrew....thank heavens there are members of the royal family who do good for the nation. My mum was once at a dinner at which he was present and says that him and his cronies were throwing bread rolls around, the sort of behaviour that would get you thrown out of wetherspoons. And the waste when people go hungry.
