Corporations are writing the laws. I can understand people not trusting the government but I cringe at how many people have a child like faith in the private sector. An underregulated Wall Street nearly destroyed the economy. If you don't acknowledge the potential for private sector abuse and disaster then there's no reason to take you seriously.
To be clear, Wall Street is regulated.
The Housing bubble was caused because the lending industry was not regulated. I recall that when I refined my house to get a lower interest rate in the 90's, it was done in the rented offices of a loan originator, not a bank.
That loan was made and then sold, 3 times before it was paid off, and that is what created the housing bubble.
The loans made created a risk, but that risk was not born by the original lender. The loans were bundled and sold and a large enough percent were bad and became the now famous "Toxic Assets" that TARP was supposed to clear up, but that are still in existence and still a ticking time bomb thanks to the ill directed and probably corrupt Obama administration dupes.
Banking and Wall Street are both pretty regulated. The Loan originators were not in such rigid constraints and the Congress of the USA passed laws to push lenders into lending to this who could not repay and should never have been given the loans in the first place.
Do you want to know who is responsible? I'll tell you. It is the people and the government of the USA. We all had a hand in it and trying to deflect blame to others is pointless and Liberal.
