Why do people farm so much plat

[goodle]

Then go and spend like 80k on a mana stone when they could space out the money and accomplish 10 times more. In my mind its like going to a bar and buying the most expensive bottle of champagne they have to get drunk when I could go to the liquor store before hand , get a four loko or 2 for 3 dollars and be hammered . I guess it all stems back to how rich people act in real life, blowing tons of cash in retarded ways..... just because they can.
