When I attended college in Michigan, our tuition increases were directly correlated to the economic status of our state.
Our governor was implementing policies that created a surge of income for the government, but years later it would create a worse economic situation. For example, trailer license plates changed from being a yearly renewal to a permanent plate. The income from that decision was substantial, being that the new price was ten times the renewal price, but the next year there would be no income for those trailer renewals.
