school uniforms make students equal?

For

If children wear uniforms, they do not notice differences between children from rich and from poor families. __source__

School uniforms equalize economic diversity and reduce social stigma. __source__

Against

In a democratic country, school should not indoctrinate children with a specific political ideology, especially not a government-funded school. __source__

School uniforms may make all students look alike. But why do the teachers not wear the same uniforms? Clearly, school does not like any confusion as to who is the teacher and who is the student. The master-slave relationship that is so obviously present at school is deliberately magnified by uniforms that emphasize this difference. The teacher is allowed to dress casually, while the student has to wear silly clothes intended to make the student look stupid. __source__

Furthermore, there are often different uniforms for those in higher grades than for those in lower grades, just like in the military a superior officer wears a less silly hat. This creates class differences. Some will argue that this merely reflects existing differences. But the point is that if this were accurate, it constituted an argument against uniformity. Moreover, school itself creates class differences. Class is a trademark, if not an invention of school. Children are grouped together in classes according to age and often according to gender and to perceived academic performance. Because parents want their children to mix with children of their 'own class', they carefully select the neighborhood where they are going to live. Houses close to private schools are often substantially more expensive than similar houses close to state schools. __source__

School uniforms emphasize economic differences. The habit of wearing school uniforms originated at rich schools, with the intention to distinguish their students from others students, i.e. from other (poorer) schools. Uniforms were first introduced by rich schools, who liked to parade their students in uniform, to show off that these were students from rich families, proud to be rich! Typically, a school serves a specific area and the difference in wealth between families that live within the area is not that much. By comparison, there's much more difference in wealth between families that live in a poor area and those living in a more wealthy area. The students who attend the school in the wealthy area will wear different uniforms than students who attend the school in a poor area. __source__

The poor kids still wear the threadbare, worn, cheaper quality uniforms with the generic, cheap sneakers or shoes, while the wealthier kids wear the namebrand, quality uniforms with the namebrand sneakers/shoes. __source__
