Extra moves purchase

Why doesn’t the get extra moves option (at the end of a failed level) increase anymore? Now it just stays on +5 moves instead of increasing to +30 after several fails. It doesn’t make good sense to me to use 10 gold bars to purchase 5 extra moves! And, I just can’t justify spending a lot of $ to advance in a game. There’s enough inflation in the real world, we don’t need it in our Candy Crush world, too!
