Imagine you are a bank manager and someone wants you to invest a huge sum of money in his new factory.
What does it make? Clothes pegs.
A new design of clothes peg? No, same as the old one.
Er....a cheaper clothes peg? Nope. They cost very little as it is, these will be a fair bit more expensive.
So the world is well served for cheap clothes pegs. What is the point of this new one? He just wanted his own clothes peg factory.
Some years ago the American military developed a mapping system which can position an object within... well it's probably a millimetre by now. And they offered this system - not quite as good as the military's but down to a metre - free. You pay nothing for satnav, it's a gift. You just pay for the gizmo which works it.
So what did Europe do? Started their own of course (they're bureaucrats, not bank managers). Firstly with the Chinese, then when the Chinese got tired with the indecision and bureaucracy and developed one on their own, they continued alone. It has cost billions - we'll probably never discover quite how much - of our money.
Yesterday the satellite launched - years late and massively over budget - and went into the wrong orbit.
Now there will be more money wasted, to obtain something that is already free.
