Textbooks: Dictating your future

Textbooks of a school, a state, or a country reflects, how it is going to shape up itself in future. Textbooks are something available to most of the people of a country at a rate they can afford. Taking this to their advantage, government has made it their Facebook, they could publish or hide whatever they want. Removal of Tienanmen Square massacre from Chinese Textbooks, Thomas Jefferson from US, subtle parts of history in India, and Portraying Palestinians as only some kind of peasants in Israel are a few examples of this kind. Do we the People, don't have any rights to know the truth about the history? Is government so free to erase past, change the present and shape the future they ways it suits to them? Are we still living the era describe by George Orwell in "1984"? I really love the last quote made by economist in an article related to textbooks: "A trip to Wikipedia by way of a smartphone will not necessarily let children work their way out of such dichotomies. But it will help." Hope we won't do something that we deem necessary to hide from our progeny.
