It’s the second point which is more interesting. If we use pre-tax income as our measure of inequality then changing the taxation system doesn’t change inequality, does it? We could double the taxation of the rich and the Gini, as we’re measuring it, would still be 0.50. We could halve the taxation of the rich and our Gini would still be 0.50.
That is, the action you’re proposing would have sod-all effect on the problem you identify and wish to correct.
Now, it’s true that you made good money in business. Well done you. You didn’t have that success by diverting scarce resources to pissing up a rope. So, why are you proposing for the body politic what you’d laugh out of your own boardroom?
