I seriously think it is only a matter of time before ads end up in textbooks issued to schoolchildren.

I can imagine it in the US at least.

Chapter 3: The Indian Removal Act

The Indian Removal Act of 1830 was signed into law on May 28, 1830, by United States President Andrew Jackson. The law, as described by Congress, provided for an exchange of lands with the Indians residing in any of the states or territories, and for their removal west of the river Mississippi. Tribes such as the Cherokee were forcibly removed by the United States government in a march to the west that later became known as the Trail of Tears.
