How exactly is not having this extremely speculative stock and currency trading running at the timespan of milliseconds became 'having to do everything for themselves'? Or are we speaking of the market where i buy groceries?
This needless back-and-forth trading can be immediately eliminated with 5% tax on those operations (i.e. you sell stock or currency worth $1000, you pay $50). Hell, 1% would cut much of crap out (5% may be too severe). Would it make everyone 'have to do everything for themselves"? Let's look, I pay sales tax whenever I sell anything I make for actual consumption, it's way more than 5% , and it didn't force anyone to do everything by themselves.
What is the problem with high-speed trading in your opinion? I see a lot of people wanting a Financial Transactoons Tax, but I have yet to see étaples of what it would accomplish or prevent?
