The political class, to cover its own irresponsibility, is trying to dump the economic crisis on the central banks. The job of the central bank is to maintain price stability. When central banks are also asked to ensure economic growth, full employment and even consumer protection, they will fail — because they have the wrong tools.
On Saturday, the European finance ministers agreed to lend Spain 100 billion euros (about $125.4 billion) to bail out the Spanish banks. The money will be wasted unless the Spanish and the other Europeans get on a high-growth track. To achieve high growth, they will have to greatly reduce entitlement spending, rigid labor policies and counterproductive regulations. How likely is that? France, rather than increasing the retirement age, which is necessary for fiscal sanity, just reduced it last week. Shorter working lives means less output and economic growth and, over the long run, less tax revenue. Yet, the French, along with the other European national banks, are going to lend money they do not have to cover loans made by Spanish banks for unproductive seaside villas.
President Obama and his allies are now claiming that the reason U.S. job growth has lagged is that not enough new "public sector" (i.e., government) jobs have been created. Which creates wealth — the government hiring another bureaucrat to produce more paperwork for a gas-drilling company to fill out, or the gas company hiring another worker to produce more gas? The Fed can print more money, and Congress can increase taxes in order to hire more government workers, but if their "work" increases the costs on business as a result of more regulations or other impediments, businesses will be hiring fewer workers. If the new government workers are not doing anything that actually increases people's standard of living, they are merely a dead weight on the economy, which decreases the money individuals and businesses have to create real wealth.
A school teacher in the classroom who teaches kids to read is creating real long-term wealth. An education bureaucrat demanding more paperwork from teachers, thus reducing the classroom teacher's time spent with students, is a wealth destroyer. Most of the increase in education spending has gone to create wealth destroyers, not wealth creators. Cutting government employment by getting rid of the wealth destroyers will be more than offset by the creation of productive jobs in the private sector.
The Keynesians love to talk about the jobs "multiplier" effect from more government spending. This multiplier only exists in the minds of those (such as New York Times columnist Paul Krugman) who are blind to reality and the empirical evidence — and have no understanding of how the public and private sectors actually operate. Mr. Obama's famous trillion-dollar stimulus — like previous big-spending programs — did not produce the jobs that its advocates claimed it would.
The law of supply and demand has not been repealed. If the cost of labor and capital is reduced, more people will be hired. The government can reduce the cost of labor and capital by reducing taxes and destructive regulations. Demand can be increased by allowing people to keep more of their own product. Central banks have the tools to create money — but not wealth — by reducing the value of private savings, which are diminished by inflation and low or negative real interest rates. Most government activities destroy wealth, and most private-sector activities increase wealth.
