Over the last 19 years, the Nederlander’s enterprise certainly has put that truism into practice, as you will know if you have seen “Hamilton” six times already. This has been to the city’s benefit: it has raised its stature in the theater world and, without question, had a significant economic benefit for downtown Chicago. Back in 2000, I wrote of my unease about having all three of the major downtown theaters (the Oriental, the then-Shubert and the Cadillac Palace) under one management, effectively freezing out theater-owning competitors like the Shuberts, the Jujamcyns (who once owned the Royal George Theatre) and, more recently, the aggressively acquisitive Ambassador Theatre Group from Britain.
