The argument that day traders provide much needed liquidity in the market is mostly a farce. Perhaps it is still true in commodities, but for stocks, ETFs, and options? No way. Liquidity is nearly 100% backed by massive MMs. Day trading could dry up tomorrow and the market would go on. I think there's a lot of ego in day traders. Unless you're swinging multiple million share positions you're not even a quarter of a blip on the radar of an S&P stock. Too many people still live in the hey-day of trading. Today in CURRENT_YEAR there's virtually no need for day traders of any kind. You may even argue they cause more problems than they are worth.
The tax makes fundamental sense. It's excessive but as long as it's leveraged fairly across both retails and majors I'm willing to bet the markets will fall suddenly (as you expect) and then stabilize into tracking value once again. The CAPE ratio is absurd. For this we can thank day traders driving prices to absurd levels. Go ahead and tell me why TSLA is trading at something like 2000x earnings. It's not because it's a good company.
