I like your intro. It has a nice way of flowing nicely when you describe one generation to the next.
Before I begin, I would like to state that as of right now; we are America's near future
I think you need a colon after "I would like to state this as of right now" and maybe eliminate near.
Before I begin, I would like to state that as of right now: We are America's future.
Other than that i there really isn't much to comment on. I think your fist sentence will work great for a speech. Try to write the rest of the speech/essay, that's really the only way you'll get some truly meaningful feedback.
Good Luck
