First of all, don't jump to conclusions, who says they stay in the lower leagues for gems? 25 gems every (week/month idk) isn't worth staying in low leagues. They stay in low leagues because they don't want to face level 100 monsters. In gold league where I used to be at, there are level 100 monsters all scattered over the place, you simply cannot progress into higher leagues with level 60 monsters.
