Option 1 (Focus on broad negative consequences):
> School budget cuts have devastating consequences, leading to increased class sizes, reduced educational resources, and ultimately, a decline in student achievement and overall educational quality.
Option 2 (Focus on a specific consequence):
> The most significant consequence of recent school budget cuts is the erosion of vital extracurricular programs, limiting students' access to enriching experiences and hindering their social, emotional, and cognitive development.
Option 3 (Focus on a specific demographic):
> School budget cuts disproportionately harm students from low-income families, exacerbating existing inequalities in access to quality education and limiting their future opportunities.
Option 4 (More nuanced perspective acknowledging potential positive aspects, but ultimately focusing on negatives):
> While some argue that school budget cuts can lead to increased efficiency, their negative effects—including larger class sizes, reduced teacher support, and fewer resources for special needs students—far outweigh any potential benefits, ultimately hindering student success.
The best option will depend on the specific focus and argument of your paper. Remember to tailor your thesis statement to your specific evidence and analysis.
