The title is funny. In pop culture we really only hear about price inflation. In fact there is monetary inflation and price inflation. They are often connected but not always connected. I'm sure there are others on SN that explain it better than me.
If you inflate a supply of anything you reduce its scarcity and almost always its value. That is, if the good's value is truly understood by the market. This is my theory on why bitcoin isn't worth X on the market today. Very few understand it. But prices of good can deflate during a time of monetary inflation. The example I always think of is anything electronic. Because technological development has outpaced monetary inflation for a very long time. We do not see the level of price inflation for these goods that we would otherwise see.
What I've realized though the average Joe doesn't give a flip about monetary inflation. Only price inflation. This isn't lost on the bankers who have been robbing the public due to this ignorance.
