The game doesn't hand out gold, the DM does, at his discretion.
The
conclusion of the blog seems to be that
because 5e players no longer need large quantities of gold to buy magic items to keep their characters viable, they don't need to be given so much. This makes sense.
The game doesn't even require the players to collect gold, though most players I know will do so, just on principle. But it's unkind to be over-generous. Give a player a million gold pieces and you give him a headache: how to move ten tons of metal, where to store it, and how to guard it against being stolen. The least of his worries is what to spend it all on. More fun to place a warehouse full of 200
Folding Boats and see what the players do with them.
