When comparing the GDPs, Instead of saying compared it to, you might want to type, "in comparison." A few transition words also might help the piece become a bit smoother. Other than that, good job on the writing! It seems very well researched!
Its good to include thoughts, feelings, what was special about it..describe to the reader what it was like
One of the causes for America's 2009 economic crisis was the invention of subprime mortgages, for 'second class' clients, who previously did not have access to credits, but the innovation of securitizing these mortgages arose, clients paid only interest the first years, making the quotas lower, but the interest rates were variable and then they were increasing and the salaries were being eaten by those payments, the central bank allowed the rules of the game to be changed, because of the crisis that was coming, this left thousands of Americans unemployed and without homes. In all this the government did not intervene favorably, on the contrary, after a while it helped the financial system to recover, but no citizen could do it.
