'Taste' discrimination - discriminating against persons on the grounds of their sex or sexual orientation, skin colour, religion or race, is largely illegal. The biggest impact of these laws has been mainly in the half of the economy in which unfairness, nepotism, crooked practice and favouritism were rampant - the socialised public sector. Capitalism, you see, tends not to discriminate on taste grounds, but only on grounds of productive efficiency. The capitalist doesn't care what colour, sex or faith his widget-makers are, only that they're the cheapest and most productive widget-makers on the market. You'll generally only find taste discrimination at the smallest end of the enterprise economy - mom 'n pop stores, and now the ubiquitous Skleps. Harland and Wolff's total bar on employing Catholics was not on theological grounds but on the basis that the inhabitants around its shipyard were so deeply sectarian that to employ both was to reduce efficiency.
It was London Transport of course in the late 50s / early 60s in a final desperate attempt to recruit native Londoners for the thousands of bus driver and conductor vacancies that published job adverts claiming frankly 'We don't employ Blacks'. Well, they failed to recruit white staff - and did exactly that, giving thousands of West Indian immigrants a real stake in our nation and society. And this sort of blatant taste discrimination in the public sector persisted well into the 1990s. My local borough recruited its entire refuse collection crews from three families - not a woman nor a black face amongst them. It made them, I was told informally, easier to manage. Their lucrative wedge was collectively negotiated with the three family heads.
Whereas a manager working for shareholders simply doesn't have the freedom to indulge their anti-competitive and inefficient personal tastes, a public sector manager is free to employ as many inefficient, underskilled, non-productive and uneconomic workers as they wish. By 2005 when threats and widespread internal dissatisfaction had put an end to my Council's discriminatory employment practices to allow in a melange of races and even some women to the 'refuge' the result was a real fall in wages and an increase in productivity - as the CIPFA stats for those years painfully demonstrate.
So the public sector, and its spiritual home the Labour Party, are quite free to vent their personal discriminatory tastes against Jews, Saxons, Catholics or whomever they wish. And such freedom attracts racists and zealots into the public sector and into the Labour Party. So of course Labour are Jew haters - what's the surprise?
