This thread was helpful for me, and I Iike beating dead horses.
For the scrub averse: soak for a week in ___(Something oxidizing like Oxy or B-Brite, or a surfactant like laundry soap)___. The longer you can go, the more the glue will be loosened and dissolved.
I've had good results with 4 day soak in B-Brite on bottles from a large corp that puts fancy foil at the top:
Foil doesn't bend and fall away so glue tends to stay, but it comes off rubbing with your thumb. Rub no scrub. Or just put it back for a few more days, zero scrub. Cheers

I humbly suggest that bicarbonate isn't active enough to make the job easier. (It certainly is easier on your municipal water treatment plant and the environment, however.) And as other say it depends strongly on the size of the beer company. Maybe the big assembly line machines can use cheap glue.I have found that regular baking soda soaking works wonders on most labels. I use the already old stuff in my fridge that has been absorbing odors rather than from the cupboard.
I have found that most labels that have shiny foil in their design tend to be tough as nails. You also learn which ones work best and which don't. I also look for the number of labels. A neck label or small promo label on the back, while probably using the same glue, just makes more work. After soaking and peeling, there is often some glue left. A small plastic scrubby normally gets it off with little work. If you have batches, soak in a bucket and pour your soak water back into the bucket for the next batch....
