But as everyone from Paul Krugman to Simon Johnson has noted, the banks are so big and politically powerful that they have bought the politicians and captured the regulators.
In addition, as Fortune pointed out last February that the only reason that smaller banks haven't been able to expand and thrive is that the too-big-to-fails have decreased competition:
Growth for the nation's smaller banks represents a reversal of trends from the last twenty years, when the biggest banks got much bigger and many of the smallest players were gobbled up or driven under...
As big banks struggle to find a way forward and rising loan losses threaten to punish poorly run banks of all sizes, smaller but well capitalized institutions have a long-awaited chance to expand.
Nobel prize winning economist Joseph Stiglitz noted in September that giants like Goldman are using their size to manipulate the market:
"The main problem that Goldman raises is a question of size: 'too big to fail.' In some markets, they have a significant fraction of trades. Why is that important? They trade both on their proprietary desk and on behalf of customers. When you do that and you have a significant fraction of all trades, you have a lot of information."The giants (especially Goldman Sachs) have also used high-frequency program trading which not only distorted the markets - making up more than 70% of stock trades - but which also let the program trading giants take a sneak peak at what the real (aka "human") traders are buying and selling, and then trade on the insider information. See this, this, this, this and this. (This is frontrunning, which is illegal; but it is a lot bigger than garden variety frontrunning, because the program traders are not only trading based on inside knowledge of what their own clients are doing, they are also trading based on knowledge of what all other traders are doing).
Further, he says, "That raises the potential of conflicts of interest, problems of front-running, using that inside information for your proprietary desk. And that's why the Volcker report came out and said that we need to restrict the kinds of activity that these large institutions have. If you're going to trade on behalf of others, if you're going to be a commercial bank, you can't engage in certain kinds of risk-taking behavior."
Goldman also admitted that its proprietary trading program can "manipulate the markets in unfair ways". The giant banks have also allegedly used their Counterparty Risk Management Policy Group (CRMPG) to exchange secret information and formulate coordinated mutually beneficial actions, all with the government's blessings.
