And you're forgetting that government and politicians played a large role in this mess too. Do you believe government can and will "protect us from ourselves"?
Let's see here - we'll go by the ideology of your beloved left. Government is controlled by Wall Street and banks and corporations to serve their bidding at the expense of the people. Obviously. The solution is to place blind trust in those who are controlled by Wall Street and banks and corporations and who sell out the American people time after time after time, with the task of protecting the people against Wall Street and banks and such.
So, genius, how specifically do you see this agency playing out? I mean, you have to be specific. You have to know more details than "my party supports it."
Let me put it another way - how much faith will you have in this agency when Republicans gain full control of congress plus the White House? Will this agency be a good thing or a bad thing when it is controlled by Republican policies and ideology? You fully support this agency, you must also fully support the consequences of the agency in future years.
New Deal structure largely prevented political manipulations of finance by either party being in power, just as constitutional structure prevents abuses in other realms of our lives.
The consumer protection agency is an attempt to impose such a structure on the financial industry, to prevent the conflicts of interest that make up any systemic financial scam. It's not really well named, because it attempts to protect the whole economy more than individual consumers.
What did we really gain from the financial innovations of self regulated banking in the ownership society, anyway? From 30 years of Reaganomics?
What we really gained was much greater concentration of wealth, income & power into the hands of the few at the expense of everybody else through the substitution of credit for wages among the vast majority of the population, and the substitution of borrowing for revenue by govt.
The other thing we gained was a top heavy & very fragile financial system that only creates wealth for the few by extracting it as interest & economic rent from the rest of us. It's fragile because it depends entirely on the ability of the scammed to keep paying the scammers, and on govt bailouts of the institutional means of the scammers, the banks.
It's the way that Repub leaders made it & want to keep it, despite any sort of misdirectional simulated rationality they can create to convince us otherwise. They believe in unregulated capitalism, yet the boom/bust nature of unregulated capitalism is highly destructive of the middle class. They don't care, because that's not who they truly represent, at all. They represent the rich, for whom both the boom and bust sides of it are just opportunities for profit & further consolidation of power.
