"It is a small but important point - A tax break does not involve the Government giving you money, it is the Government taking less of your hard-earned money off you."
Except we're talking about banks and people with, was it "more than £100,000 to invest"?, and the money is taken off you by the government 'to invest in others', possibly the arms industry, possibly a disabled single parent but 'we' are choosing to invest in a bundle of start-ups instead, with a chance of making more profit for us.
In my experience, money given to me looks a lot like money not taken away, in almost all circumstances. Here, it's money being taken from me anyway being put at risk in the hope of money being given to me later. It's a bit like being a minor Lloyds Member at zero personal risk.
I'm fine with the government using state resources taken from the comfortably off, to invest in startup companies but here it seems to be doing that as a side-effect of a tax dodge for the wealthy. It's the government that bothers me, not those benefiting from it.
