Are Investment companies sitting on cash or do they have it invested ?
Not sure what investment companies you are talking about but no investment companies sit on cash. They have it invested somewhere, maybe a low interest yielding term deposit, but something, high risk or low risk.
Oh, and they don't deal in cash. They invest money that somebody else has invested in them (also known as borrowings). Investment companies that use their own money for investing end up broke or no better off.
The only they all make money is using somebody else's money.
That's why there should be a financial transaction tax. Every time the money moves it is taxed. And a sliding scale for how long the "investment" is held.
Tax out investing in crap like CFD derivatives and forex shorts and promote investing in companies that manufacture and produce.
Get rid of the computer generated micro-second transactions.
Every financial crisis these days occurs when the ever spiraling roundabout of credit flow is disrupted. It isn't real money and never was. Crisis these days doesn't happen when the potato crop is down 20%. They happen when the futures market is down 20% or the re-insurance on sub-prime debt derivatives take a dive.
Maybe Bitcoin has its use ?
Use it for financial markets that want / need to gamble and leave real money for the normal people. Bitcoin crashes and just the gamblers hurt.
