Control Spending to Cut Taxes

Houston ISD has a spending problem. HISD now has six consecutive budgets that have run budget deficits. While HISD still has a robust "rainy day" fund, the fund will not continue to last if the current spending spree continues. The coronavirus pandemic has been an excuse for spending, but taking a closer look at the numbers suggests otherwise.
The HISD web page link for budget information (https://www.houstonisd.org/Page/68701) gives scant information to work with. Looking at the six years worth of budgets available shows the following deficits shows that the yearly deficit only exceeded 5% one year. It's also noteworthy that the numbers are a combined M&O and I&S presentation, and that both elements were at a deficit spending level. This suggests that the budget, while not at sustainable levels, isn't so out of control that reigning the budget in will be a painful process.
The M&O tax rate is at the highest rate allowed by law. HISD needs to make a change so that the tax rate can be lowered. Keeping the tax rate at the highest allowable level is simply bad public policy. If crisis arises and a transient income boost is needed where will the district get the income if the tax rate cannot be raised?
