I think what's more "unfair" about this is that there actually is information which implies that it's the paralegal who is pregnant. The "X married Y because she was pregnant" scenario is more likely when Y is going to be put in a particularly bad way because of the scenario, and X can reasonably take care of her. It's also more likely to occur when there's a power imbalance, where X is more powerful than Y, and therefore feels responsible to "amend for" the situation.

"Male attorney gets female paralegal pregnant" matches both of those templates pretty well, and so "...and so does the responsible thing and marries her" fits. "Male paralegal gets female attorney pregnant", not so much: The power / provision dynamic there is completely different, and so "...and does the responsible thing and marries her" doesn't really follow. If they end up getting married, it's because the more powerful and more highly-paid attorney decided that's what she wanted to do, not because she was making the best of a bad situation.
