The counter-argument, of course, is that these two things go hand-in-hand, that these new establishments cater to would-be gentrifiers and not the people that already live there and while, yes, the Pilsen neighborhood is safer, quieter and now has more amenities than 20 years ago this doesn't do anything for the established residents if they're being pushed all the way out of their neighborhood due to rapidly rising rents.
I wouldn't call this my personal take on what's going on in Pilsen, but I think about it a lot. It's also a big reason why I'd never consider moving there. I'd rather not be viewed as an invading force on my own block.
I'd argue that gentrification was at full steam by the time Rev opened their brewpub location (rents were already shooting up and the area directly around the square had become fully brunch-ified), but that stretch of Milwaukee is definitely a portent of what will become of 18th Street if there isn't something done to help working-class people stay where they are, either by rent control or improved economic opportunities.
First come the gastropubs, then the mid-rise condos. You'll know it's all over when it's announced that a Lululemon store is coming to the neighborhood.
