well, consumers aren't suposed to think about this...actually economy works exactly because they don't think about those problems:p
btw I'm not an economist but I think that there are many variables which may interact with each others, for example:
it is known that around 2008-2010 the answer for petrol will surpass the offer, which should cause a raise of its price, and therefore a raise of the cost of almost any goodies. This is due to the progressive increment of the oil answer from the asian (chinese) economies...what will happen to em? On a side note, this is probably one of the reasons for china interests in the iran nuclear projects.
What about the US estate market, which became so necessary to fuel the consumptions through the private debt..
I'm not sure it is really possible to fully preview the result of all the interactions but surely what can be seen (and what many say) doesn't make me very optimistic
