Ok - I'll run with your proposal of a clear link between government incentives such as cuts to corporation taxes and periods of economic growth. I'm admittedly out of my depth here but willing to learn. So I googled to try and find the clear historical links that you are proposing to be "common sense". I looked at the top 5 articles and it made interesting reading:
http://www.economicshelp.org/blog/21...ease-revenue/: The writer speculates that "For example, if UK cut corporation tax rate to 15% and others maintain the same tax rates – you could expect it to increase inward investment and possibly tax revenue for the UK. However, if others follow suit and cut to the same rate, there will be a very different effect. The UK will not gain any competitive advantage from the tax cut" and goes on to say "If this does occur, the main beneficiaries are companies who get to keep a bigger share of profit. The taxpayer loses out because income and expenditure taxes have to rise to compensate". In short, the writer agrees with you in theory but has no evidence historically that it will happen, even suggesting that companies keep the difference.
Ok - so how about article 2?:
http://www.epi.org/publication/ib364...onomic-growth/
The writer here concludes that: "On the surface, it would appear that more robust economic growth is associated with higher corporate tax rates. Further analysis, however, finds no evidence that either the statutory top corporate tax rate or the effective marginal tax rate on capital income is correlated with real GDP growth".
Article 3:
https://www.brookings.edu/research/e...onomic-growth/ concludes "We find that, while there is no doubt that tax policy can influence economic choices, it is by no means obvious, on an ex ante basis, that tax rate cuts will ultimately lead to a larger economy in the long run". This writer doesn't write off potential gains: "A fair assessment would conclude that well-designed tax policies have the potential to raise economic growth, but there are many stumbling blocks along the way and certainly no guarantee that all tax changes will improve economic performance".
So, three articles quite randomly surfed seem to show no evidence for your assertions. You say that you rely on "history" so to save me any more searching please could you point to historical instances of where corporation tax cuts have had a demonstrable affect on wealth creation in our economy (I am genuinely inquiring and open minded on this, but you make HUGE assertions that Corbyn's way of raising money for services (and of course there is no statistical definition of properly funded, that's an admittedly loose term but how else do we measure it? I guess what we should say is to raise enough money to make a demonstrable improvement (let others do the measuring!) on public service investment) is negative and your way of creating wealth (through corporation tax and other tax incentives) is right. As I've said before, Labour's proposals are a risk, but why should your proposals be any less of a risk as there appears to be (as yet, I'm sure you may be about to throw something at me!) no actual foundation for them?
Just an addendum: Your throwaway comment "who said life is fair?" is quite telling...
Deal with sources for my statements on tax amounts later 'tater. Gotta get back to work :-(
