To have a quota to make?

Hiya!

I'm in a translation of a short cartoon (sort of), and there is a part I find difficult to grasp.
More specifically, this sentence: "And they’ve got that quota to make."

Here is a longer extract of the context where it's from:
"And then you get out of grade school you go to high school—and it’s revving up, the thing is coming…
Then you’re going to go to college, and by jove then you get into graduate school, and when you’re through with graduate school, you’ll go out to join the world.
And then you get into some racket where you’re selling insurance. And they’ve got that quota to make. And you’re going to make that.
And all the time, this thing is coming, it’s coming, it’s coming—that great thing, the success you’re working for."

Can someone give me just a short explanation what it means actually?

Thank you in advance!
