Women and immigrants can be upper middle class.

I also think this feels like pandering to prejudice and might even make things worse by encouraging people not to take those people seriously unless they have the right title.

You also still do not need huge numbers of job titles to try and indicate an exact level, nor title inflation.

I am quite surprised that title inflation has not caused more problems than it has. Its been awhile but IIRC UK law (and other common law countries I would guess) will hold a company to a contract if the employee was made to look like they had the right to agree to it - and calling someone "director" might well do that.
