I dont think taxing them will accomplish much. its also trivial for corporations to evade taxes, and all of the big ones do.
I think the ease of raising money is part of the problem. Loads of tech companies way over-raise, and develop into bloated cancerous messes that have no way of ever realizing the growth that would have to exist to warrant the investment theyve been given.
In the first place, the only way their investors even expect make anything back would be by reselling the stock, making it a ponzi asset.
The entire system is just propped up by peoples 401ks being funneled to institutional investors. Its inherently unstable.
Make social security good enough that middle class citizens dont need to invest, and the overinflated value of stocks plummets back to earth.
WHERE DID THE COWS GO
