I think your wrong Bcram, I think its very much on the agenda, maybe not at the % rates above but it's one of the easier ways for govt.
Hundreds of billions will not be recouped with 2 or 3p on income tax.
Remember there wasn't gonna be a Brexit, Jeremy Corbyn couldn't win the labour leadership election and salmond was going to jail, trump couldn't win, and the Tories would never bring in the poll tax.
Never say never.
