Stock market is not fit for purpose
The current Uk financial services industry does not invest in anything.
They just asset strip, either by forcing the management to hand over dividends each quarter by cutting costs, cancelling needed investment or selling of assets.
If that does not work then selling to the first foreigner that comes along.
Great for bankers bonuses.
However there is no investment in new technologies, innovative companies . Worse when the overseas owner gets into trouble they shut down the foriegn operations -- i.e. the UK operation because its easier and cheaper to sack workers there. Even worse valuable brands are squandered, how long before you hear the word "Cadburies" and think YUK?
