In his first televised speech before Congress, President Obama asserted that prosperity will return once the government restores the flow of credit in the economy. It may come as a surprise to him, but an economy cannot run on consumer loans. Furthermore, credit stopped flowing in the U.S. for a very good reason: there was no more savings left to loan. Government efforts to simply make credit available, without rebuilding productive capacity or increasing savings, are doomed to destroy what's left of our economy.
The central tenets of Obamanomics appear to be that access to credit will enable people to borrow money to buy stuff, the spending will spur production and employment, and thus the economy will grow. It's a neat and simple picture, but it has nothing whatsoever to do with how an economy works. The President does not understand that consumption is made possible by production and that credit is made possible by savings. The size and complexity of modern economies has obscured these simple concepts, but reducing the picture to a small scale can help clear away the fog.
Suppose there is a very small barter-based economy consisting of only three individuals: a butcher, a baker, and a candlestick maker. If the candlestick maker wants bread or steak, he makes candlesticks and trades. The candlestick maker always wants food, but his demand can only be satisfied if he makes candlesticks, without which he goes hungry. The mere fact that he desires bread and steak is meaningless.
Enter the magic wand of credit, which many now assume can take the place of production. Suppose the butcher has managed to produce an excess amount of steak and has more than he needs on a daily basis. Knowing this, the candlestick maker asks to borrow a steak from the butcher to trade to the baker for bread. For this transaction to take place the butcher must first have produced steaks which he did not consume (savings). He then loans his savings to the candlestick maker, who issues the butcher a note promising to repay his debt in candlesticks.
In this instance, it was the butcher's production of steak that enabled the candlestick maker to buy bread, which also had to be produced. The fact that the candlestick maker had access to credit did not increase demand or bolster the economy. In fact, by using credit to buy instead of candlesticks, the economy now has fewer candlesticks, and the butcher now has fewer steaks with which to buy bread himself. What has happened is that through savings, the butcher has loaned his purchasing power, created by his production, to the candlestick maker, who used it to buy bread.
Similarly, the candlestick maker could have offered “IOU candlesticks” directly to the baker. Again, the transaction could only be successful if the baker actually baked bread that he did not consume himself and was therefore able to loan his savings to the candlestick maker. Since he loaned his bread to the candlestick maker, he no longer has that bread himself to trade for steak.
The existence of credit in no way increases aggregate consumption within this community, it merely temporarily alters the way consumption is distributed. The only way for aggregate consumption to increase is for the production of candlesticks, steak, and bread to increase.
