True. But this is the source of the problems with our economy. His job acts as a maintenance cost and therefore adds no value. The problem is that we are a nation of consumers and spenders not producers and savers. The only way to achieve real growth is through captial - capital are produced goods and savings. Consumerism does not equate to economic growth. Sure he can feed himself but if you look at it from the long term it is a net drag on the economy. It has to be good for the butcher, the baker and the candlestick maker. Long, I know but here is the essence of what non productive jobs do for the economy:
"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 candles and trades. The candlestick maker always wants food, but his demand can only be satisfied if he makes candles, 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 candles, the economy now has fewer candles, 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."
Replace credit for jobs "created" by regulatory agencies that are non productive and you can see the long term problem of appreciating jobs created by regulations and bureaucrats. Same goes for the U.S. Government - they produce nothing and only redistribute the wealth they steal from others.
