I find the predictions are many things that are already happening or near so. The layoffs, the small business closures, the rich not spending (it is where spending is down, it's not poor people whose spending has gone down), the local governments crunched for money.
But I just find the suggestions dubious, put all one's money in cash? Really? Eliminate debt? I don't know if housing prices go down an equally good case could be made for taking out debt to buy. I don't carry or even cosider the possibility of other debt unless I was forced into it by circumstances (which actually is how much debt is acquired - medical debt etc.). Gold and silver, have some if you want as a sort of diversification play, but how much good will they really be.
