ladymuck You say "When you consider how many non-white people there are in politics and who have high positions in society ..... it is obvious that the opportunities for advancement are there."
An article in the Guardian in 2017 (https://www.theguardian.com/inequality/2017/sep/26/employees-on-workplace-racism-under-representation-bame) included this information:
"New research conducted by the Guardian and Operation Black Vote has found just 3.5% non-white faces at the top of the UK’s leading 1,000+ organisations, compared with 12.9% in the general population...
In 2009, the Department for Work and Pensions embarked on an experiment, seemingly motivated by a desire to understand the causes of this longstanding problem... Civil servants concocted more than 2,000 fake job applications in response to 1,000 real vacancies across multiple sectors, professions and pay grades. According to the Mail on Sunday, officials entered very similar (made-up) CVs for each job, “one under a traditional Anglo-Saxon name, and [another] using an ethnic minority-sounding name.
"....................Theresa May, then the Conservative shadow minister for work and pensions, called the project “a waste of taxpayers’ cash”.
"The results, however, appeared conclusive. Applicants with white, British-sounding names were far more likely to be called to interview for a position than their ethnic minority counterparts.
" ................At the end of last year, a report by the centre-right thinktank Policy Exchange concluded that, despite a growing BAME middle class, ethnic minorities in highly skilled, well-paid professions are concentrated at the bottom level of senior management roles.
........ "In her recent review of race in the workplace, Baroness McGregor-Smith found that people of colour are much more likely to be overqualified for their jobs than white counterparts, who often advance up the ladder of promotion with ease. ...."
If racism is not responsible for this significant under-representation of non-white people at senior levels in commercial and public organisations, what do you put it down to?
