You can always recognize a Leftist by their Zero Sum thought processes.
Providing an advantage to one person does not necessarily create a disadvantage to another person.
In this case there can be no disadvantage to another persons child by reading to your child because there is no irreplaceable resource expended upon your child by reading your child a bed time story.
Some other child will not have the advantage of bed time stories but that is not a disadvantage it is simply an advantage not realized.
However the story deprived child may ultimately be advantaged by the stories your child enjoys by your child growing up to be a more productive person. More productive people enrich society as a whole. The rising tide lifts all boats meme is reality regardless of how it is demeaned by the Left.
I wholeheartedly agree with your post. You make more sense than a gaggle of university professors.
