Why are we in this financial crisis?

So why is GCISD in this "financial crisis"?  

• GCISD's revenue from the state is still based on 2005 numbers.  It's like working for a company and not having had a salary increase since 2005, but having increasing expenses due to inflation, etc.  Cost of living increases are estimated at 2% each year.  
• How does GCISD increase it's revenue or make more money?  The only ways to increase revenue are to either (a) raise the M&O tax rate which can only be raised through a tax ratification election to voters (TRE); or (b) increase student enrollment.  Well, GCISD didn't want to have high tax rates back in 2005 like some of our surrounding districts so the tax rate was set at $1.04 instead of the $1.17 cap--if our tax rate would've been higher back then, we would have more money now.  Also, people like living in this area and don't move very much--there aren't a lot of young families moving in while families with older kids who have graduated move out.  We're also pretty land-locked, so it's hard to increase student enrollment.
• The state of Texas is working under a huge budget defecit ($27 billion shortfall in its revenues) and is cutting its funding across the board, including public education.  Public education represents about 44% of the state's budget, therefore equalling about $10 billion in cuts.  The revenue GCISD receives from the state represents about 17% of the total sources of revenue (82% from local taxes, 0% federal and 1% other).
