There are absolutely benefits to breast milk over formula, but that doesn't mean that it's the only option or that women need to do all of the child-raising on their own.

Ideally, mothers would receive ample maternity leave to cover the breastfeeding period, fathers would receive ample paternity leave to cover the weeks immediately after birth and the period after the breastfeeding period ends, and both parents would be working part-time most of their careers.

Ultimately, dual-income has turned out to be an ugly bait-and-switch. The point was that women were more free, more independent, more able to develop themselves professionally, and families would be able to live more comfortably with the added income. Instead, it has often lead to families requiring two incomes to even be able to afford a house, mothers having to mix raising children while working while fathers still didn't do their part.

We should all be working a maximum of 24 hours a week by now. We were screwed out of these benefits and all the benefits of this increased productivity has gone to the rich instead of to working families.
