I assume you write this as a bad thing?<p>Its better for economy if brokers would focus on long term trades. Also usually high-volume low-profit businesses are the ones that are arbitrating prices and often are just middle man. No need for that. There is a way around. Obviously there would be FEW businesses that would be affected and need to change the way they work, but this comes always with any tax changes.<p>Anyways, I said all revenue that hits your account. Brokers usually don&#x27;t keep their money in bank accounts, but in investment accounts, right? Until the money hit their actual bank account they would pay null on trades. So they would pay tax on all withdrawals and payouts to customers.
