A proposal by the tax payers alliance & a group of CEO's.
Now... call me cynical...
But perhaps (just maybe) this is an attempt to get those at the top (Who already yield the greatest benefits of society) to pay even less to sustain it.
According to the first figures, it could cost £50billion PA in lost tax - increasing the deficit significantly, then you have to take it on faith that it would yield economic growth (which I highly doubt as the spending power of the public, IE the people who buy the goods, would be stretched even further).
I'll leave to floor to people who will personally benefit from this to try to justify yet another tax cut for the top few percent at the expense of wider society.
