You would be blown away at how many people without money spend $4000 in a short time.

I worked with a guy who spent thousands on World of Tanks when it launched 12years ago (free to play, and they didn't have anything that was pay-to-win or that resembled gambling). His income was about $40k and he had a family to support. I have since run into others who have blown similar amounts or more on mobile gaming. These people are slowly, quietly ruining their lives.
