The tendency has been for services and products to always expand. I remember when automobiles did not have seat belts and radio and heaters were optional. The auto of today has gadgets unheard of 50 years ago, and most have wrap-around, stereophonic sound systems. The marketing of autos has dramatically changed, and so has the marketing of education. It seemingly takes a larger volume of business to provide the product and stay in business.
Finances are also a continuing cause of change.
Also, they are much more likely faced with reorganization as an alternative to going too far into a financial abyss. The State's role has varied over time. The state was very aggressive during the 1950s and 1960s. It closed many schools for not meeting the standards, and this carried a message to others. The recent period of reorganization found the state offering financial incentives for reorganizing and sharing.
