Given the rumoured $10B that vista cost, it is hopefully a lesson that MS won't forget in a hurry.
So how much did it cost to run Bletchley Park over a similar time period:
Current data is only available till 2006. In 2006, £10 0s 0d from 1943 was worth:
£309.05 using the retail price index
£334.63 using the GDP deflator
£985.32 using the average earnings
£1,037.88 using the per capita GDP
£1,287.70 using the share of GDP
paying 7766 people £10 a week to work there would have cost ten million pounds at an exchange rate of £1 in today's money to £128:15:6d.
For 5 years that is a bill of £19,415,000.
I have no idea how much they earned but some would have beenon senior college staff wages and some on senior civil servant's wages which I am guessing is about the same.
And some would have been on girl's wages as school leavers. And I have no idea of the numbers involved. A factory worker would have been on good money. They would have had to come close despite any cachet working in an office would bring in those days.
Current data is only available till 2006. In 2006, £19415000 0s 0d from 1943 was worth:
£600,016,360.13 using the retail price index
£649,688,122.50 using the GDP deflator
£1,912,991,719.14 using the average earnings
£2,015,036,809.43 using the per capita GDP
£2,500,076,311.69 using the share of GDP
Two thousand five hundred million pounds.
All of it to be spent in Britain, the ultimate lock in.
