This idea of what is money and what is wealth is a hard one to get your hands around.
Ask yourself... "How much money do I have?" Well, I have about $35 in my wallet, but that is about it. In reality, all of my money is held in an account somewhere. Virtually all of your money is being held on an accounting sheet somewhere. "I have money in my checking account"... no you don't, the bank has already lent 90% of that money to say
Super-Duper Computer Store. That is the way wealth is created. Both you and Super-Duper Computer think they have that money. Indeed Super-Duper Computer has hard assets in the form of computers sitting on the shelf in their store.
You don't have money in the bank, you have an IOU from the bank. It isn't 'real' money. In fact, you didn't put 'real' money in the bank in the first place. You put your paycheck in the bank - which was an IOU being transferred from your employer's bank to yours. So you didn't get paid in 'real' money either.
In the United States we all operate on the principle that our institutions can be trusted to hold our wealth and the number printed on the page is indeed our money. But it is all an illusion. The only difference between money that you have in the bank and money you have in the stock market is that the FDIC guarantees the money you have in the bank. But even that is a matter of risk. Your money in the bank is guaranteed by the full faith and credit of the government. If the US banking system and the Federal Reserve were to go bankrupt like has happened in many other countries, then we would all be losers.
In the final analysis, it is all a matter "of how much risk do you want to take?" Money is at risk even if you put it under your mattress - over time it will dramatically loose value simply by inflation.
I always like the quote from the film
Gone with the Wind:
"Why, land is the only thing in the world worth workin' for, worth fightin' for, worth dyin' for, because it's the only thing that lasts."
But in the recession, we have seen that even the price of land is not free from risk. All of life is a risk, and wealth is never "safe" no matter where you keep it. The secret is knowing how much risk to take - and at what time.
