Donald Trump isn’t the first president, or even the first Republican president, who has sought to define his legacy in part with a big construction project. Abraham Lincoln signed legislation providing the land grants and financing that created the transcontinental railroad. Theodore Roosevelt built the Panama Canal. Dwight Eisenhower built the interstate highway system.
But Trump’s wall is different, and not just because it probably won’t actually get built. Previous big construction projects were about bringing people together and making them more productive. The wall is about division — not just a barrier against outsiders, but an attempt to drive a wedge between Americans, too. It’s about fear, not the future.
Why isn’t Trump building anything? Surely he’s exactly the kind of politician likely to suffer from an edifice complex, a desire to see his name on big projects. Furthermore, during the 2016 campaign he didn’t just promise a wall, he also promised a major rebuilding of America’s infrastructure.
