&gt; You can pretty trivially expand the question as to why woman are choosing their careers over children.<p>The problem is that it&#x27;s not just one problem. Almost everything is set up to economically discourage two-income families from having more children. After everything you&#x27;ve mentioned, the second income financially disqualifies you from many childcare and other benefits available to single-income families while progressive taxation, sold as targeting the wealthy, instead swallows the money a middle income family could have used to pay for those things out of pocket.<p>And after the government has laid claim to most of the second income, what&#x27;s left becomes the baseline for the cost of living. More families now have two incomes so it takes two incomes to afford a home in a good school district.<p>It seems what is needed but not present is a strong lobby for middle class families. Everyone pays lip service because they&#x27;re a large voting block, but where is the equivalent of the AARP or NRA for families with children?
