I don’t think your premise that it is going to grow more in terms of impact size is valid. It’s already eaten the US stockmarkets (and a number of others).
So I don’t think anyone has the power to make that choice between keep or pop later, but if it was possible then slowly deflating the bubble and regulations to prevent this sort of thing happening in the first place would be my answer. Not going to happen of course.
Out of the bad alternatives of the bubble popping now, and the bubble popping later, later would be better for we non-americans if we had govt’s who would actually work through the things needed to reduce its impact.
So, here in reality, damned if it does now, damned if it does later, either option is ugly.
I’ve been telling all my friends to get themselves and their pensions out of shares (US in particular) for the last 6 months I doubt they listened but what else can you do ?
