Corbyn believes that when a country like the UK currently has £1,600,000,000,000 (£1.6 trillion) of National Debt, an additional £1,200,000,000,000 (£1.2 trillion) of unfunded State & Public Sector Pension Liabilities (to come out of annual government spending budgets when fall due) AND a current annual government budget deficit/overspend of £70 billion - any plans to sort ANY of that out, is called austerity.
Corbyns wants to spend countless £billions nationalising UK businesses, despite trying that in the 'good old days' which failed, needing constant injection of taxpayers money in the meantime.
Corbyn does not like the Private Sector/businesses that CREATES the several hundred £billion of tax revenues each year to fund the UK State's Public Sector, welfare, benefits, tax credits and pensions - and will drive them away with ever increasing taxes.
Corbyn believes there are £billions of businesses taxes not being paid that no one in the either the last Labour government or the Conservatives have bothered to collect.
Corbyn can not get his head around that between 50% & 60% of the largest companies in the UK represented within the FTSE 100 are foreign owned, so ONLY PAY taxes on their UK operations e.g. Boots, not the earnings on their GLOBAL consolidated earning.
In our words Corbyn is a prize prat that shouldn't be allowed a credit card never mind running a country's finances - as ALL the socialist La La Land dreams could not be afforded if the UK's current finances was half as bad - but as thanks to the last Labour administration it is not, and a country can't put its national credit card in a draw and hopes it goes away.
The day ANY socialist MP stops calling the trying to get the debts of the last socialism experiment under control and start to paying it down austerity, they might, just might have the makings of half a brain to run the UK.
