1. Collapse of tax revenue as anybody who can, will look to leave the country. The result being the Labour party will seek to hit people in the £40k pa bracket to try to plug the spill.
Where is this magical land people can relocate to and use the same skills to earn the same or more but pay less tax? Is it where the unicorns live in the magic money tree forest? Very, very few people will do this in reality, and those who do will leave behind a gap in the economy for others to fill.
2. 30-40% fall in the value of house prices across the country as nobody wants to be seem to have 'capital' in an political environment , where 'rich' or wealthy is open to interpertation.
Not sure what you mean by that. People will own property either as a necessity or as a means of income. Neither will stop simply because they "don't want to be seen to have capital".
3. Inflation as everybody gets paid £10 a hour a supervisor than requires £15 a hour pushing inflation through the roof.
It's not that black and white. Generally speaking higher wages means increased spending and a boom to the economy. Of course this will differ from business to business but on the whole the country will benefit from higher wages.
4. The raft of social changes and extra taxes that will be imposed on 'small' business. These being such as regarding working time restrictions on staff increased NI contributions to cover black hole caused by the black hole of Capital flight and talented people leaving. A major damage being 'cottage' business will no longer be able to exist, the sole trader or two three people employer will be unable to exist !
This is nothing but scaremongering. The major issues this economy faces is not from small business or sole traders, it is from trillions of pounds leaving the economy untaxed to foreign accounts and never returning, while wages that actually circulate within the economy and generate tax from every transaction are kept low.
4. The net result will be yes a reduction in the gap between the wealthy and the 'poor' but that is because we will have just reinvented the system that caused the brain drain in the 1970s.
I think you mean 5. Perhaps we should do a Diane Abbot on you and suggest that if you can't even count to 5 we should take any economic forecast of yours with a massive pinch of salt.
Ultimately it will be up to the government of the day to set the tax rates and policies in a way that maximises tax revenue and stimulate the economy. You might not think a Labour government would and you're entitled to that opinion, but clearly this Conservative government has done neither and the opinions of the worlds economists and their condemnation of their atrocious and chaotic handling of the economy has got to count for something. This hasn't worked for 7 years and things are worse now than they ever were. Expecting anything to change by continuing with the same is utter madness.
