The Daily Telegraph article shows the extent of the flight but there are important lessons to be learned.
Many people in the UK have doubted the wisdom of cutting the 50% income tax rate to 45%. There is a feeling that it is 'fair' for the rich to pay more than the middle income earners. This may actually be a reasonable point, but the argument is that the disincentive effects of high tax reduce overall economic performance and so make everyone worse off in the long run. While 75% is a lot more than 50% in tax terms there seems to be credible evidence that incentives do matter.
France has been incredibly slow to adopt supply-side reforms. The French industrialist Louis Gallois has delivered a report calling for 'shock therapy' to help improve French competitiveness. His plan includes cutting payroll taxes for employers, spending cuts and higher consumer taxes. There seems little political will to do this. Hollande is an old fashioned socialist who has no experience of government and ideals are yet to be overcome by reality for him. France carries some of the highest labour costs in the world and with a rapidly expanding trade deficit and 27% youth unemployment the Gallois Report may be the thing that comes back to haunt him at the next election.
A further important point to note is the fall in the French money supply that has resulted from the capital flight. This is potentially serious as it represents a deflationary force in an economy already in recession. Falling money supply is going to reduce AD and prevent recovery. In situations like these deflation is the last thing the economy needs and so the French cannot ignore the loss of confidence the capital flight represents. Like so many socialist leaders before him Hollande must realise that it is not possible for a country to be the sole master of its economic policy.
