Yup and thats part of the issue. Too many people want to simplify it down to, "if we just did x, then we will see y." Nah, this is a complicated problem. Its probably gonna take the whole alphabet of solutions, but there is no political will or too much squabbling to since people want their idea why we have population decline to be right. But the bottom line is, having kids is expensive. You can make it less expensive, but that alone probably isn't gonna solve it.
