Book Errors and the Future

It is of no use to deny any errors in the publications and textbooks written and given to the Filipino Students today, it was obvious and is not just a few, but "too many few" to mention, is it right?
The problem with this is not limited to the cost of the book, although these books used in the public schools are low-cost, it should not be a legal reason to sacrifice it's quality. Quality that is should not only be limited to spelling and grammatical errors but also should include a check on the contents of every page. This is the standard, before these books are delivered to every school, there is a group of teachers who will review it. Are these teachers assigned to review the books really reviewing? I know one of them who were assigned to review and yet failed to distinguish errors on the written matter! Some reviewers are not really capable of reviewing, either not interested reading or not capable of reading. Something must be done!
On a TV interview, one author said that there are just few minor errs on his book, do we say that on the standards, we allow few minor errs for our students to make? We mark them wrong on their report cards and even give them low grades especially if the "few minor errs" were of critical nature. What about the publishers editors? How come this "few minor errs" came into the light of National Issue?
The most probable cause and root of this problem, is still, graft and corruption! I agree to "Ka Oca Orbos" when he said that corruption is the root of all these. With a low-cost public text book, the Education Department can save millions of pesos, some to be reserved on someone else's personal projects. The rampant red tape and "whom you know" among the low rank teachers will defer the inclusion of qualified teachers to join the team of book reviewers. Ever wonder how our education system collapsed and bring forth today's children with both extremes of highly intellectuals and very much illiterate students? To whom should we attribute this happenings, to the teachers? to the Bureaucrats? to the Policy-makers? to the Implementors?
I don't know. If I will be asked where to let my child take his education, I'd probably answer at home where I can supervise everything my child is working at.
