^Agree with that. It goes with the “show, don’t tell” advice we give to college applicants. If the OP’s D really wants to impress ad-coms, she will get her hands dirty – working toward passage of minimum wage legislation in her area, volunteering at food banks or shelters for people who don’t have as much as she does, volunteering for a political campaign. That will give her some experiences to tie to her strong opinions, and give her a chance to make the essay about herself – grand pronouncements aren’t helpful in essays.
