I appreciate your concern, and I appreciate you speaking up about this.

I thought the phrase might sound as you say it does, but I've decided to leave it as is, with the following reasoning:

"Should" here does not indicate agreement, as you've well picked up from the rest of the message. "Should" here indicates that what's happening is within the order of things, given the circumstances. It's meant to imply that, should circumstances change, the object — the prominence of the pick-up culture — shall change accordingly with them. "Will" here would give a false sense of permanence to the derogative and inhumane culture, which I recognize to be an inaccurate description.

I know I'm no master of the English language, but I think studying its grammar to the letter has given me an insight into how it works enough to justify playing with the language on the same level as its native speakers as long as I can afford it. I appreciate an outside perspective, of course, and if you think I made a mistake, I would appreciate it if you — or anyone with an explanation — would correct me in the future.
