The current US TFR would be more than enough to grow the population if the female to male ratio of births were sufficiently skewed. In the limit of a mostly female population, a TFR of just above 1 is enough to sustain the population.
So perhaps the problem isn't increasing the number of births per woman, but rather increasing the fraction of the population that are women. Women already do better than men in college; perhaps if women are perceived as having better economic prospects, and if technical means of choosing the sex of children were available, parents would tend to choose female children.
