That many American students, even those in high school, are poor readers has been evidenced by numerous studies though the solution is simple and inexpensive: having their parents read to them during toddlerhood.
The human mind has the capacity to induct the nature of reading if this task is presented properly, just as it does with the grammar of the language of the country into which a child is born. Thus a child born in France learns to speak French and a child born in Spain learns to speak Spanish. Not by learning all possible word combinations which it has been written would take a hundred-thousand years, but by inducting the nature of their nation's grammar.
In a similar manner a child can learn to read if, as a toddler, their mother or parenting figure holds them closely and reads to them while running their finger under the line. Using this technique most children will be reading simple books by the time they begin kindergarten. With no cost or the price of a book or trip to the local library. So why doesn't the government push this?
