Answer:
In simple words, what this means is that if everyone was stuck, the world would be too.
Step-by-step explanation:
Advancement is produced by people, if people did not have goals in life they would be stagnant.
That means that the world would not advance, we would always be in the same place because we would all be satisfied with what we have, without aspiring to more.
With the goals of each of the people on the planet, day by day we advance more and we will continue to do so while everyone aspires to more.
