Let’s begin at the beginning. What is wealth? Wealth is not more paper money, obviously, for otherwise Zimbabwe would be the wealthiest nation ever. Wealth is useful things that you own. This is true both of an individual and a nation.
Your friend says the govt can create wealth. The govt does not own factories, so it cannot create wealth that way. All it can do is print paper money.
But your friend claims that printing more paper money can be a catalyst to create true wealth. Now, true wealth is created on farms and factories. And often a farm or factory could produce even more things [=wealth] if it could improve its machinery. The farmer who has a tractor can grow more than one who has only his bare hands. The factory with more modern machinery etc.
But how will the farmer get that new tractor? What if he cannot pay for it? So your firend has the answer. The govt will print more money, give it to a bank who will presumably lend it to the farmer, and he will buy his new tractor. With his new tractor, he will be able, over the years, to produce so much more that he will be able to pay back his debts with interest to the bank and still have a profit. He is wealthier, the bank is wealthier, the nation has more food to feed it, all praise to the govt printing press.
But the question arises, why couldn’t the farmer get a loan of pre-existing money? Why did the banks have to loan him newly printed money? Has all the money that existed so far been burnt up as cigarrette paper? The only possible answer is that he was considered too big a risk by those who have money to make it worth their while to lend it to him. The odds are, they figure, that this guy will not run his farm well, tractor or no tractor. They would rather lend their money to someone who is a better investment, in their considered opinion. But the newly printed money, which the Fed got for free [by printing it], well what are they going to do with that? They have already lent to the good investments. May as well lend this new stuff to the risky farmer. After all, we got the money for free [or at very low interest], there is no one else to lend it to, and the govt will probably bail us out if the guy won’t pay.
That is one problem with printing money. It goes to riskier ventures. This is exactly what happened with the nasdaq and housing bubbles.
But even should the farmer succeed, somebody is getting robbed by this whole transaction. There is a law of supply and demand. It applies to everything. It states that the greater the supply of something, the lower will be the price of that thing. Everybody knows this. When there is a bumper crop of wheat, the price of wheat will be cheaper.
And the same applies to money. When there is more money in existence, its “price”, meaning its purchasing power, goes down. Imagine if everyone on Earth was given a trillion trillion dollars. Would gasoline still cost 3 dollars a gallon? Of course not. Because more people will buy cars and will want more gasoline. But there is only so much gasoline to go round. A bidding war begins, increasing the price of gasoline. The same is true of everything that is for sale, to a greater or lesser extent. This is called [price] inflation, and it’s a direct consequence of money printing. So that maybe the banks profit, maybe the farmer profits, but everyone else who didn’t get free money loses, because the purchasing power of whatever money they do have, and that they will get in the future, has sunk.
This is not a theoretical thing. It has happened over and over again. One of the posters here wrote a long list of countries that have experienced this to an extreme degree, called hyperinflation.
I replaced Steve Jobs with the farmer, but the idea is the same.
