4. A brief list of better questions for billionaire presidential candidates

Flashbacks:

• 2007: Rudy Giuliani was asked the price of milk and bread. (His answers were not particularly close.) In 1992
• 1992: George H.W. Bush was asked the price of bread. "I'd say ... it would cost you about a buck a loaf." (He was right.)

The big picture: Billionaires may be unlikely to know what a grocery item costs, and their actions as president would have limited effects on prices.But they should know the broader trends in the costs that most Americans face.

1. Health care: How much has the average health insurance deductible for a family of four changed over the past 5 years? How about copays?
2. Education: What's the average price of tuition at a public 4-year university? How much has this outpaced inflation over the past few decades?
3. Kids: What's the average cost of child care in your home state? Is this a greater share of take-home income than it was 10 years ago? 20?
4. The youths: What percentage of 25-year-olds have more than $50,000 in student debt? What percentage of 25-year-olds have purchased a home? How do these compare to 10 years ago?
5. Housing: How much of the average American's monthly paycheck goes to rent or a mortgage?
6. Rainy day funds: How many months of living expenses does the average American have in liquid savings?

Why it matters: “[T]he next president will have to demonstrate not only that he or she understands the day-to-day struggles that people are facing, but they also have to lay out a clear plan to address those problems," Center for American Progress SVP Daniella Gibbs Léger told Axios.Go deeper: Livid liberals try to bully Schultz out of 2020
