>>18053719>printing money magically increasesthere's your problem, it's not magic, it's simple math.
Principally, if you have a Money Supply, let's name it M1, and a total amount of stuff, your prices will be determined by how many dollars there are vice what the lowest earning is (as the average person will not work a job for a wage they cannot sustain themselves on), giving you basic prices based on factors involved in producing the product or servicing a client (i.e. some groceries are cheaper than others in a given location based on how close they are to the source).
Now, imagine you add more money to that M1, that total money supply. You now have more dollars chasing the same stuff, so there are more people willing to pay more money for the same thing over time.
Sure, we can get even more real world and explain what happens with the walmart/amazon effect, criminality, etc. But you said explain it like a 31 year old's listening, so there's your failed millennial explanation.
