Okay. The subject briefly came up in all of my history classes. At least as much as “some slave labor was used in the building of the original White House. Of course there had to also be carpenters and stonemasons who were from a variety of backgrounds. I also learned that James Hoban, an Irish immigrant designed the White House. I apologize. I didn’t realize that that subject was not covered at all in other people’s elementary, middle school and high school American History courses, let alone college courses. I thought it was commonly taught, like the fact that while George Washington was the first President of the United States of America, John Hanson was the first President of the Continental Congress. Or that before the Capital was moved to Washington it was located in Pennsylvania and then New York. These are all things that were repeated over and over and over again throughout my early education in Ohio, Washington state and Pennsylvania. I assumed, incorrectly apparently, that that would be the case in other school districts.
