PROBLEM: We simply have to reduce the cost of educating public school students.  We spend like $18,000 per student and this amount is ridiculous and unsustainable.  School administration must be reduced.

SOLUTION: Yes

PROBLEM: "It's an election year, and candidates cannot stop talking about our country's problems(which of course, only they can solve)  As a result of this negative drumbeat , many Americans believe that their children will not live as well as they themselves do.
That view is dead wrong: The babies being born in America today are the luckiest cap in history...Indeed, most of todays children are doing well. All family in my upper middle class neighborhood regularly enjoy a standard of living better than that achieved by John D. Rockefeller Sr. at the time of my birth. His unparalleled fortune couldn't buy what we now take for granted, whether the field is - to name a just a few - transportation, entertainment, communications or medical services. Rockefeller certainly had power and fame; he could not, however, live as well as my neighbors do now."
