This comes off as a statement made by somebody who actually doesn't know this city well. Maybe that's not the case, but I don't think your statement is quite the solid argument you intended. It's far more complex than "plain and simple," and the generational conflict you are suggesting as the impetus is just plain silly.
I wasn't suggesting a generational conflict... I was actually talking about the normal trajectory of people who partake in late-night night life... its predominantly something that 20-somethings do. Eventually you age out of it and its no longer an issue worth worrying about.
Same reason the drinking age is 21 though a large number of people think its stupid. Once you're past it... it stops being a problem.
Boston's 20-something population either eventually ages out or moves out and so we stay the way we are.
