The problem is how do you get people to increase their investment, time and energies if more of the rewards are being taken from them?
I agree we should be paying more tax but I think we should ALL be paying more tax. The collective is the absolute principle of socialism by the way.
Put it this way, someone earning £150k doesn't earn £150k, they actually earn £90k. That is 40% of their salary is taken from them, do you think its fair they should lose more?
The top down approach by Mcdonnell is not good, it is easy. It is easy because it is easy to sell to most people (voters) who aren't rich because it won't affect them. Will it raise the £500bn Mcdonnell needs though to do everything he wants to do? Not a single chance.
