Ause & Effect of Americas Social Security Crisis

I need a 500 word essay, that includes in its intro paragraph a clear thesis stating the causes (not opinionated) that have resulted in Americas Social Security crisis. Causes need to include, references from the geriatric revolution, birth control, etc. I need the causes to nearly cover the first page, with 250 words. And the other half of the 250 words to describe the effects of how Americas Social Security System came to be a crisis from its primary causes with an appropriate conclusion that sums the essay up. I can not have any opinions in this paper. please just only facts. Thank you.
