Baby Boomer generation is 1946-1964, which would make them 59-77. I expect only the younger range is likely to still be middle managers. Maybe it's just me, but I feel like the use of "boomer" as a derogative to be reductionist and ageist, not to mention most of the time incorrect, as I've seen it applied all the way to Millennials.
They've been criticizing my generation for receiving the "participation trophies" they gave us as kids, as well as screwing over our entire economy with shortsighted self-protectionism, so I definitely mean it in a derogatory way against people their age. To be fair, I criticize them for the shit they did when they were my age too, so I'm criticizing them as a cohort, not because of their current age.
Are you sure that the people doing the criticizing are the same people giving out the trophies?
> so I definitely mean it in a derogatory way against people their age
The way you had used it, as commentary on middle managers, seem to include people from Baby Boomers all the way to Millennials.
> I'm criticizing them as a cohort, not because of their current age
In which case it sounds like using the age identifier would be incorrect.
