The reduction of recommended quarantine time was clearly an acknowledgement of this. Keeping it at two weeks with no way to significantly reduce infection rates would have led to a month of everything being shut down, and everyone still getting sick anyway. Hell, it may yet lead to a week or three of de facto shutdown, just from actual out-sick time. The folks in charge have given up, without explicitly saying so.

[EDIT] For some evidence that we may get a de facto shutdown anyway: our (large) school district was short three hundred teachers the other day, and only managed to get one hundred subs. The schools are barely hanging on and shutting down or going remote for a week or two to cool things off and/or wait out the peak is a distinct possibility, which will have knock-on effects for the rest of the economy, which is also already dealing with high absence rates due to illness or direct exposure (which, with Omicron, is equivalent to "definitely has it, just waiting for symptoms").
