There is going to be a correlation that those who have many books at home are likely to be more educated than those who do not and that as a rule those who are more educated are going to have higher incomes. There is also going to be a correlation that those who have more books at home and read them are going to be more curious about the world than those who do not and this curiosity, too will lead to a higher income statistically. My father is a humanities prof. at a major university who had thousands of books in his home office that we would read as children growing up. We would discuss books and ideas at the dinner table. Thus, in effect we children received a liberal arts education at home. Today, with a $75 kindle people have access to great libraries for many of the classics are freely accessible. Shakespeare, Twain, George Elliot, Dickens, Shaw, ... all free to download and read. Moreover, many ebooks still under copyright can be checked out electronically from public libraries and read. The studies reported of course were observational. It would be interesting to prospectively perform a study placing books in a number of households and seeing how children develop over 20 years.
