Her problems: Many Americans can’t afford medical care....many parts of our public school system suck....
The real problems: Many Americans are unhealthy, many Americans lack the skills necessary to get a job. When you prematurely narrow the problem, you can't identify all solutions.
Jolie's premature narrowing of the problem makes it impossible to think of some solutions. If you think the problem is affordability of health care, you'll never think of a healthier lifestyle. If you think the problem is that public schools suck, you'll never think of scrapping them and replacing them with some alternative.
