It is not a 0 sum gain. Goldman has to pay out 2,500,000 and they took in mainly $500,000 at most. They have to default on the payment or go bankrupt.Derivatives were the main cause. Do you even know what a derivative is? In this case it was an investment that would hedge a mortgage by betting it would default. If you allow one derivative per mortgage it is a zero sum game. But the law allowed for one mortgage to back multiple derivatives. If the mortgage failed there would not be funds to pay off the many derivatives. It puts a multiplier effect on bad mortgages. That caused many financial institution to default.Less regulation of mortgages contributed to the recession. That was driven by Republicans. Making mortgages easier to obtain was driven by Democrats. The biggest driver was the approval of derivative by both parties.Tonight rump blamed Obama for the debt under his administration.
1) Most of that debt was due to the Bush Administration's worst recession in 80 years as the deficit in 2009 was estimated to be over a trillion even before Obama took office.
2) Trump had made no improvements in the deficit since taking office despite taking over in a the midst of the longest streak (broken by Trump) of job gains & low unemployment
3) If you want to see huge deficits again, let Trump pass his tax plan. The Bush tax cut was a major part of that Great Recession
Democrats caused the Great Recession with their mortgage policies and then blamed it on Bush.
Bush's tax cut got us out of the Tech Stock Bubble recession.
Left Wingers are dumb.
But ultimately it was caused by greedy bankers finding ways to take advantage of the above to make excessive profits and then bailing when they had the excessive losses that came with the risky investments created.
More regulations would have caught the slime buckets.
These simple minded people who want to blame one party on a simplistic interpretation that is false.
Trump supporters want everything to be simpler than it is.
The root cause of the Great Recession is liberal culture which produces lower class people who don't pay their bills and who have bad credit. That is why Clinton lowered the mortgage lending standards.
You are correct that the democrats made mortgages easier to get for low income people but the bigger driver were banks allowing middle and high income individuals to qualify for loans they should not of.
You obviously have very little knowledge of investing and our banking system.
If you allow one derivative per mortgage it is a zero sum game. But the law allowed for one mortgage to back multiple derivatives. If the mortgage failed there would not be funds to pay off the many derivatives.
It's still zero sum.
If Goldman insured the same $500,000 mortgage, 5 times and the mortgage fails, Goldman pays out $2,500,000 and the insured parties receive $2,500,000.
It puts a multiplier effect on bad mortgages.
How many mortgages had a CDS written against them even once, let alone multiple times?
Probably a really small number.
That caused many financial institution to default.
How many firms went under because they wrote CDS?
How many went under just because they wrote/held crappy mortgages?
