I've read (here and here etc) that Sam Altman was the one behind the high memory prices by tying up 40% of the DRAM market for his company, without actually committing to purchasing the RAM. This YouTuber talks about the whole situation. I like how he calls him "Scam Altman"
America is corrupt to the core, allowing these tech billionaires to take over like this. Lobby with enough money, and they buy laws to protect them too.
