I was a little less cerebral in my thoughts. A national insurance hike favoured by Labour will cost jobs.
Companies should pay their fair share tax-wise, but they should be taxed on their profits. They should not be taxed by the number of employees they have, because that will influence them to trim their workforces and not take on new recruits.
This is one of the craziest things Labour have ever come up with.
When a company makes profit, they can either 1) pay tax on it, 2) distribute dividends to shareholders, who will then pay tax, or 3) employ more people, who will pay income tax. Win, win, win!
Taxing jobs will not raise revenue because the jobs will disappear.
