Are the banks at it again: Facebook = sub-prime mortgages?

[Chosen Man]

Facebook have not posted any accounts, it is estimated their revenue ( note: not their profit) is 1.5billion, yet Morgan Stanley Bank paid 300million for 1% of the company (valuing Facebook at 30bn GBP) and are now selling more shares - for a slice of the sale price and commission.

The .com boom of the 1990s caused mayhem when it collapsed because of unprofitable and over inflated IT companies.

Sub- prime markets failed because of unprofitable and over inflated mortgage packages.

Are the banks doing the same now, over inflating prices on unprofitable companies, because they know that the taxpayers will bail them out?

Is this a new share bubble?

Will you be happy at your taxes paying for this new gamble when it goes wrong?

Your thoughts please.
