This hyperbole makes your point very easy to disprove. All it takes is one example and your statement is factually incorrect. Italy, South Korea, etc. Many definitions of "developed" basically boil down to income so you would basically need the USA to be the least developed of developed countries. But I will try and be charitable and assume you mean USA labor costs are on the low end of developed countries.
What metrics are you looking at? Wages in general in the USA are higher (higher median income). The 15$/hr example I used is higher than most minimum wages in Europe. For example the minimum wage in Germany is about 1600 euros a month or $10/hr for full-time work.
Regardless, even if US labor costs are low relative to developed countries (which doesnt seem to be the case), it doesnt change that its a major factor in daycare costs and that increasing wages would just make very high prices even higher.
In 2022 the US had a lower minimum wage than every OECD country other than Romania, Croatia, Hungary and Czechia.
21 developed countries have more expensive labor than the US, and only 4 are less expensive.
Labor in the US is cheap among Developed countries.

California, for example, would be at the very top in 2022 ($15/hr). a mid CoL state like Illinois being $12/hr in 2022.
This is definitely the case with other countries too, but the US's (relatively) weak federal government is a consequence of this. They leave the states a lot of autonomy in these matters but set a bare basic floor to prevent obvious abuse. As a result, the federal minimum wage hasn't increased since 2009. Wheras states tend to increase every year or 2 (calidornia increased to $15.50 this year).
According to the OECD, the US was at $15.08 in 2022... which means almost rock bottom for the OECD. So your example of Illinois at $12 is the actual rock bottom, cheapest labor in the entire OECD.
Thanks for making it so clear.
$15/hr is approximately $30k/year if you made the latter argument. US measures its minimum wage hourly so I used that site's own conversion function to save me some mental bandwidth. Which I unfortunately lost by having to reply to this. Oh well.
Labor in the US is significantly cheaper than any other developed country.
