I believe the key to this issue is to have more middle-class to increase the needs for a certain quality service. We all know good service is more than just fulfilled the basic needs. To make it more clear, there has to be more people with middle class consuming capability. We are hitting a bottleneck. If it cannot be raised in a certain period, bad things could happen. Human society has its own way to force the rebalance. However, it's quite ugly. And I wish we can avoid this.
