Answer:
I believe the answer is the last one. It seems to make the most sense out of the three.
In order to provide their children with a higher standard of living, Gloria and Matt most likely will have to work <em>a lot.</em> Working this much probably doesn't allow them to spend that much time with their kids, and they must determine which matters more to them, the well-being of their children in the future, or spending time with their kids while they're young.
Hope this helps!
