ELI5:Why are video games so expensive in Australia?
gpt
All the reasons people are giving is the reason prices started out higher.  Shipping a product overseas, higher minimum wage, etc.   
But really though, the prices are higher because enough people are willing to pay it.  They are willing because these prices are what's normal to them.  It's not like the prices just went up a week ago, the prices have always been expensive and so people don't protest the price by not buying the game they want to play.  Complaining about the price does very little.  Actually not buying it is the way to get things to change.  Video game companies (like everything else) exist to make money.  Sure, the artist and individual people enjoy making their art/whatever but the company itself exists to make money.  If it doesn't make money, it stops existing.

If you could bottle tap water and sell it for $20 a bottle.  And people would buy so much you sell out, why would you lower prices?  Hell if you keep selling out, you would raise prices!

This is the origin of a lot of sayings like "Put your money where your mouth is" or "Vote with your wallet."

Remember the price on nearly every single thing in the world is determined by what people are willing to pay.  Cars, hotels, pizza, cell phones, etc.

So until people stop paying the prices, they will stay the same.
