No, Jon,
I don't expect a second credit crunch - simply because we haven't seen the end of this one. The mortgage crisis in the USA has another step to go, when those who could pay, but are on self cert, find they can't pay. Remember, mortgages in the States are non recourse loans. As for the UK, property prices are still not affordable, so will drop further. Lending critria wiil revert to my youth (no bad thing) when you had to save with an institution for several years before you would be considered for a loan. The recent FTSE recovery is unsustainable; UK plc is bankrupt and we have no manufacturing base or natural resources. Eastern European countries bought in hard currency they cannot repay. Naive 'innocents abroad' bought ridiculously overpriced properties in places as diverse as Bulgaria, Egypt, Dubai, Morocco, Latvia etc. without knowing what they were buying into or doing the most basic research. E.G. what is the length of the ski season in Bulgaria's (low level) resorts ?. 10 - 12 weeks, so even with max occupancy your return is negative; year round resort - an investing myth. As I asked elsewhere, what is the true figure of money lost by Brit (& Irish investors) in these places.
Incidentally, did buyers from other countries rush headlong into these disasters ?.
People need to realise, the unthinkable can happen; there are no sacred cows. The Sunday Times recently ran a well balanced article postulating that British Airways could go under. Can't happen ?. Remember PanAm, TWA, Swissair, Alitalia, Sabena (Iberia next),SAS on the brink.
Our parents prudency was wise; don't spend what you don't have or can't afford to lose.
Finally, a fact I still find almost impossible to comprehend - the NHS is the third largest employer in the world !. Explain the economics behind that !.
