If it takes 155 years or so for people to decide they don't like that investment, I'd probably call that a sound investment. You could even put money into things that tend to be quite nice for people. Schools come to mind. Libraries. I'm spitballing.
Unless the plan is to build monuments to current day prison wardens. Depends how bad-faith the argument is, I suppose.
Not that it takes away from your point, but they're mostly not 155 years old. Most of the statues were put up during the Jim Crow era and during the Civil Rights movement of the '60s. You can see a graph on the Wikipedia page.
