My quick take....
The change in National Insurance does nothing for me personally as from the end of this month I don't pay it any more anyway.
The stamp duty change will probably stimulate the housing market, but will also fuel housing price rises. That may well generate activity and spending - if any "spare money" isn't being soaked up by fuel/heating costs.
The change in the highest tax rate is nothing more than helping themselves and their mates. I'd reckon that an MP salary plus a few "consultancy" commissions would put them firmly in that band.
So that's another £10,000 a year in the pocket!
All of this is being paid for by borrowing so it's the mostly you and I who'll pay for it all.
But, will any of it actually happen?
Almost everything doesn't take effect until next April.
Will it still be the same people or even the same party in control them?
