On April 15, 2019, Notre Dame Cathedral in Paris, France suffered a devastating fire. Donations flowed in immediately to restore the cathedral. Imagine if donors had told France that they could only have the money if they waived all rights to the cathedral.
That is essentially the deal the U.S. offered to the Lakota in 1980 for the Black Hills. The U.S. Supreme Court held that the U.S. government violated the 5th Amendment by not paying fair compensation when it took the Black Hills from the Lakota in 1877. The court calculated the 1877 value of the land at $17 million; then added interest to set compensation at $102 million. By comparison gold worth about $358 million was mined in the Black Hills from 1876 to 1935.
