And here is my recommendation.
If you have friends who like the way a market economy works, and who are leery of governments, buy a copy for their children. Their parents will enjoy the book as much as their children, who will learn things they would not otherwise find out so early in life.
However, for parents of a contrary disposition, buy the book for their children, as above, but never expect the book to be passed on to their children, and certainly not read to them. You will just have to content yourself with knowing the parents have read the book and then had a meltdown before throwing it on the compost heap, or hopefully passing it on to the local op-shop where someone else will buy it.
