In France it could soon be illegal to discriminate against people in poverty. Under proposed legislation – already approved by the senate and likely to be passed by the chamber of deputies – it would be an offence in France to “insult the poor” or to refuse them jobs, healthcare or housing.

Similar laws banning discrimination on the grounds of social and economic origin already exist in Belgium and Bolivia, but the French version is said to be the most far-reaching. Anyone found guilty of discrimination against those suffering from “vulnerability resulting from an apparent or known economic situation” would face a maximum sentence of three years in prison and a fine of €45,000 (£32,000).

It is easy to judge the proposed French law as showing the worst excesses of the state, or to bemoan the practicalities of how difficult it could be to implement. But most of us are content to outlaw discrimination on the grounds of race, religion, or sex. Is it so ridiculous to add poverty to that list? And if it does feel ridiculous, why is that?

Economic inequality cannot survive without cultural prejudice. The media and political rhetoric surrounding the new round of cuts – from the benefit cap to child tax credits – shows this well enough. Benefit claimants “slouch” on handouts as hardworking taxpayers toil away to pay for them. Families on benefits should reproduce – or “breed” – as little as possible. Benefit sanctions – a system in such dire straits that Iain Duncan Smith’s own advisers have warned that it needs to be reviewed – are based on the very premise that the feckless poor need an incentive to get themselves out of poverty.
