A Sticky Wicket

In this day and age of technology and fast paced living, why are stickers still so darn hard to get off an item?  To be fair, not all of them are so bad but the ones that are are real stinkers.
I carefully pull back a corner and peel so...so.....so slowly and I get about a third of it off and the rest is stuck fast.  Or when the printed part comes off and you are left with paper and glue that won't budge.  Or you get the whole thing off and there is a ton of glue on the item which you then have to proceed to get off.
I am ever hopeful, but it usually is one of those things when it comes to stickers.  I REALLY hate it when the item is going to be a gift.  Nothing like a thoughtful gift with half the sticker on it because it wouldn't budge.  Hopefully you at least get the price off.
There are a lot of really smart people out there.  Could one of you get to work on this?  Or at least could someone talk to the guy or gal who invented the few that come off clean and ask them to share their secret with the rest of their colleagues?
You can cut a tag but you can't cut a sticker and that stinks.
