No. Vulgar to talk about income and money more generally.
I was brought up that way but I’ve realised since that information is power, and by not sharing information we have less power.
There are two parties who benefit from wage opacity: employers who will push to pay as little as they can get away with (THEY know how much everyone in the org gets paid, so they have a power their employees don’t ) and employees who think they might be paid more than their peers without justification. For the rest of us, the more information we have the better.
Some of the new tech companies, who have to massively compete for good people, publish wages openly. Some even allow the employees to decide between them who gets paid what.
And in wider society, I think it’s important to know the facts about income and wealth distribution so we make informed decisions about our own finances and when making political decisions.
I’d actually like to see it taught in school, using TV families (because we get intimate views of their homes and while we know it’s not real, it is presented as realistic but lifestyles are often outside their implied income bracket - eg payday loan advert families sitting at the kitchen island - and cumulatively that gives a distorted idea of what “normal” lifestyles are)
“Here’s the Tesco Christmas advert family. Based on what we can see in the advert, to run a household like this in our town they’d need a net income of not less than £xx,000, which would mean both parents earning a full time salary of Y, or one earning a salary of Z. A Tesco driver earns N. How you think the family arranges their finances? What might be happening outside what we see in the advert? What decisions will they need to make?”
