I'm surprised how little attention that part of the story receives, but maybe I'm in the minority as a late-20s bachelor? Earnings received by a partner and shared expenses makes a dramatic difference to wealth accumulation. Where I live, if I earn double what two people in a relationship each individually earn, the couple make an extra 12% after-tax vs. what I do because they are taxed at a lower rate on their lower individual incomes. Furthermore, while two people eat and poop twice as much as one person, the greatest expenses (living) can often be shared.
