Thats not what happened when the banks regardless of contracts still gave out large bonuses many times more than the return to the taxpayers.
That simply doesn't add up.
Example: The gov only made 8.5%, but if the US costs have increased 16% over the same period (because of a depression), the overall return is more like 24.5%, ignoring the additional costs of a depression.

I'd suggest that's a much more direct and obvious economic impact than some maybe-perhaps about driving investment overseas. (How, exactly? Do you think money would suddenly stampede out of the US if regulators developed a spine and jailed the delinquent operators who caused the crash?)
Anywway - clearly the decision was political. It was made for the benefit of the banker caste, and not for the general population.
The underlying problem is unearned privilege.
There's no rational reason for these bonuses. But bankers pay themselves these sums because they know they can, irrespective of the incredible damage they cause to the rest of the economy.
But when reviewing the decision afterwards, I think we need to reject lines of argument that the government did really great on the deal so it's not that bad what happened. We don't want it to happen again, we don't want to be in a no-other-options situation.
Also the country would survive a depression if it really came down to that, the bank wouldn't survive a bankruptcy.
So the playing field are fairly even when it comes to having leverage.
