what else could be the USA’s “engine of the economy” if not consumer spending?

Question

I see headlines and articles discussing how consumer spending is driving, or of late, possibly slowing, the economy. But if not for people buying non-essential products and services, what else would drive the economy? Everyone needs food, shelter, and clothing. Many need cars, depending on their location. But I take it that spending on necessities is not enough, especially non-consumable or long lasting things like houses and cars.

Ummm, military spending?
