The tax is on pulling it out. People make small trades all the time, and computers make millions of them. It would take more time and money to calculate the taxes than the actual taxes.
Wait, so if a single thing that costs 10bucks and gets traded between companies 100 times should be taxed 100 times before it reaches the end consumer?
Do you really need to be told how much this increases prices?
There’s a tax on gains realized or something, right? But you’re right, I think, that taxing each transaction would do a lot to help redirect wealth from the ultra rich. I’ll consider it further, but I think you’ve persuaded me.
