It’s immediately obvious that increasing the money supply and spending the money will result in inflation. MMT says that the only constraint on spending is inflation, but also turns around and says that you can always print more money. That’s a contradiction. Printing more money does not change the real wealth in the economy. You can’t create additional purchasing power with an increase in the money supply because pr…
The money supply has almost quadrupled in the last 10 years, yet inflation has been low.
MMT says that spending new money only causes inflation when the money is spent on stuff the private sector is also bidding for. Since that's pretty much everything that the government would want to spend money on, MMT & conventional economics are not in much disagreement here.
"MMT says that the only constraint on spending is inflation, but also turns around and says that you can always print more money. That’s a contradiction."
You can always spend more money, but only if you tax enough back to tame inflation. It's a constraint, not a contradiction.
"Printing more money does not change the real wealth in the economy."
Exactly. MMT doesn't create goods & services out of thin air, but what it does do is unlock idle capacity in the system. If Joe Sixpack is unemployed, he's a resource that the private sector is not utilizing, but he's a drain on society because somebody is paying for his food & shelter. MMT and the jobs guarantee would utilize that resource for good, and it won't affect inflation or the private sector as long as the jobs guarantee wage is at the minimum wage mark.
