I completely agree, nice work.
HOWEVER, the part where it says uniforms inflict financial hardship on parents who are already struggling is kind of the opposite, so I wouldn't include that. I think school uniforms help low-income families by creating a level playing field that masks visible socioeconomic differences, reducing the financial pressure to purchase expensive brand-name clothing, and simplifying daily routines. That's about the only benefit to them, so if you're required to write a counterargument, then I would include this.
