ELI5: Why does adding money into an economy affect inflation? Why can't prices remain fixed and incomes rise?
gpt
Imagine that you live in a world where the only thing anybody wants is pizza, and each day one pizza is made, with exactly 100 slices, with varying toppings. There are exactly 50 people in this world, and every day, you dig holes, and for every hole you dig you get a dollar. At the end of the day, the pizza slices are auctioned off. 

One day, the money god decides to pay everyone two dollars per hole, but no more pizza is made. So now you, and everyone else, has twice as much money. But you all still want to eat, so you all bid twice as much, and nothing in the system has changed except for the numbers written on your money.
