Do you believe that investment banks actually respect the principle of a level playing field? Given the widespread fraud revealed during the 2008 financial crisis, I find that a more plausible scenario is the banks pay lip service to the idea of a level playing field and make a show of instituting a firewall, but in practice the firewall leaks information like a sieve, which the banks ruthlessly exploit for profits. The bigger the bank, the more clients they have, hence the more information they have, hence the higher the chance for insider trading and big profits.
