I agree that is a problem, particular with the concentration of power in small industries and the cultural homogenisation of people in power.

I recall in 2016 British employers who said they would fire any employees they discovered voted for Brexit - of course the only way they could find out is if people said how the voted but that is a free speech issue.

I think we need legal protections for things like free speech that we have traditionally had against governments to apply to employers and service providers. I think legislation that prevents various forms of discrimination proves it is achievable.
