When we look back in 20 years time todays prices will seem tiny, buying at this peak will seem insignificant even if prices fall 20 or 30% in the meantime. They will recover over time. FTB's are buying now because they need a home, and in the long run are probably better off not trying to time the market.
I think it would be wise to consider the long term perspective. We are by nature usually negative about the future, thats human nature, there is a bubble but we'll get over it. There is global warming but we'll probably get over it too....As far as the future is concerned, we're probably into a new era with massive new markets opening up, with huge middle (consumer) classes emerging in Asia etc. Huge possibilities lie ahead...this is not the end of the line...
