Higher/highest quality child care is not putting your kid in child care at all. I don't know why rich parents would want to risk the long term welfare of their kids so they can work more. Kids that spend lots of time in child care are objectively worse off.

> Within 10 years, comprehensive analyses of the universal, “$5 per day childcare” program, including its impact on child care use, employment patterns, and children’s and parent outcomes, suggested cause for concern. Social development among children, as indicated by both emotional and behavioral measures, had significantly deteriorated in Quebec, relative to the rest of Canada (10% of a standard deviation lower). Comparisons between children ages 2 to 4 who had been exposed to the program, with older children (and siblings) who had not, revealed significant increases in anxiety, hyperactivity, and aggression in those exposed to the program. And the analyses found more hostile, inconsistent parenting, and lower-quality parental relationships among parents of children exposed to the program. But it was hard to predict whether the negative outcomes identified for 2- to 4-year-olds would persist across their development, or simply dissipate.
> Their research confirmed that the negative effects did continue, and in some cases became stronger across development. Among 5 to 9-year-olds, negative social-emotional outcomes not only persisted, but in some cases increased, as indicated by 24% of a standard deviation increase in anxiety, a 19% increase in aggression, and a 13% in hyperactivity. The impact on boys and children with the most elevated behavioral problems was stronger, especially in measures of hyperactivity and aggression.
