Or...much simpler...much more effective:"Are you better off today than you were 4 years ago".
Simpler, but not necessarily more effective. In my experience persuading people you need to do so in a way that they can connect with. Everyone projects their own experiences onto others lives.
In this case there are a lot of blacks who resent Latinos, read Mexicans, for taking “their jobs”, etc. The illusion won’t be lost on them or others who think similarly. We need to rephrase “Are you better off now than you were 4 years ago” into every “dialect” in the American mindset.
To paraphrase an Obama favorite - “Let a million phrases bloom!”
