Lay investors buy the stock of really good companies and hold on to it. That is investing. GameStop is not such a company, and the people buying its stock have no intention of holding it and gifting it to their kids. This isn’t investing, it is trading, and there is a huge difference.
To the extent that what happened to Gamestop is a problem, it is all due to the fact that the SEC has allowed short sellers to run amuck for more than a decade now.
