The thing that creates the specific downward pressure in the US is also the thing that makes it very GDP-productive. When business raises their voice, they get to call the shots and define society in a way that creates economic rent: so, car dependency, approaches to childcare, approaches to healthcare, and so on. A lot of money from these businesses is "on the books" and easy to assess for taxation and investment purposes, and the government tends to be satisfied with this arrangement since it makes easy to know who's in charge. Meanwhile, everyone suffers from having sprawled cities with expensive homes, oversized trucks, bad healthcare, etc. All of that results in an expensive childcare number.

But this structure is also rather unrelated to the real productivity of the economy - the creatively destructive portion of American business always has something to say about it. If those companies want their labor to be cheaper and less frequently disrupted, they have to go cause grief for one of these rentier businesses, socialize some things and cut into some monopoly inaction or low standards. But they only reach that conclusion by letting the economy get into a highly unstable position first.
