I think the issue with interrupting stems from about four minutes 29 seconds into the video when Neil asks the student if she, her friends, and her family might be willing to pay more for additional benefits. She starts to say, "Yes and we already do pay more…" I just wish she would've been able to finish the thought:
"Yes and we already do pay more for college considering the rapidly increasing cost of tuition. The reasons people over $1,000,000 per year should pay increased taxes to support higher education are: high income earners are more likely to be business owners and business owners benefit from an educated labor pool [supporting evidence] and the wealthy have the a duty to support the middle/lower class for moral reasons [supporting evidence]."
I wouldn't say that there is supporting evidence to substantiate the reasons I fabricated but I was just hoping the student would counter with something substantive and specific. I'm probably being too optimistic in imagining that, without the interruption around the four-minute mark, the student would have found her footing; I'm sure some become frazzled by being in the spotlight.
In any case, even if the student is the organizational leader of the march, I wish she might have thought to tap a friend more comfortable with facts and figures to appear for the interview. Organizing a march does not necessarily mean one has the skill set to defend the principles of the march on national television.
