In Hills Like White Elephants, what does Jig mean by her sarcastic comment that "we can have everything"?

When Jig
suggests that "we can have everything"? she is actually implying that, in fact, they
cannot have everything and that the American is ignoring the fact that they must make difficult
decisions. Jig is facing the choice of having a baby or having an abortion. If she has the
illegal and dangerous abortion, she cannot have the baby. If she has the baby, she cannot
continue the free and irresponsible life of travelling around Europe that she is currently
enjoying. Moreover, if €˜everything includes marriage, the American isnt even offering that
option. Thus the comment highlights the difference between everything the American wants and
everything Jig wants.
