Your middle example is a strawman. Nobody is suggesting a raise for the richest, but a huge rise to the minimum wage and fuck everybody else is just reinforcing the spiralling cost of living.
As it stands I know a lot of people like your hypothetical team leader who've worked hard to be able to get the security of a slightly higher pay bands which will now be swallowed up by minimum wage while their cost of living increases dramatically to pay for these minium wage hikes.
My middle example was just a reflection of what had been expressed on this thread. People in the middle are unhappy that people at the bottom might get a pay rise and feel they deserve one too. That same logic will be applied by people at the top and the status quo will remain.
It's also why I had written a third example and explicitly said "This is what we should be striving for" which you've completely ignored for some reason.
Your sums simply don't work. Reducing the pay of the few top management won't finance the wage increases for the masses at the bottom. All it will do is make you feel better for "punishing" the people at the top. Typical Labour politics of jealousy and envy.
Oh ffs, it wasn't a fully costed methodology for businesses to follow, just a way to illustrate how we need to reduce the gap between top and bottom.
Denise Coates (bet365's owner/director) earned £469m last year. That's 26,056 times more than someone who works as a customer service adviser for the firm. She could afford to pay every single one of her 4600 employees an extra £80k a year and still take home £100m. That's absolutely grotesque! And, while an extreme example the average CEO today still makes around 250-350 times more than the average worker (note average not NMW). Can you genuinely say this is a fair situation to be in?
Reducing the pay of a few top managers might not solve the issue, but ensuring fair wealth distribution most certainly will. I've mentioned this before but will keep doing so until people realise just how insane the gap between the top and bottom is.
The top 1% of the UK have enough personal wealth to wipe out the UK's national debt AND end homelessness and hunger (in the UK) AND would still have circa £1 Trillion to themselves. Thats just private individuals, not businesses. There's no justifying that level of inequality but I'm sure your typical Tory politics of hatred and greed will have you disagreeing*.
*I don't really believe that but can stereotype just as well as you.
P.s. I've never voted Labour in my life.
