A nation should require all its students to study same national curriculum until they enter college

If every student studies the same national curriculum until they enter college, then it would greatly affect both student's upbringing and the society as a whole. One should remember that people are divided on the basis of caste, sex, region, religion, and many other aspects. I condemn this proposal of same national curriculum for all because of the following reasons.

Firstly, If a national curriculum is same for all, then the cost of education would be almost same for all too, as most of the teachers would need to have same expertise same as other teachers and hence would expect equal pay for all. A kid from poor family may not be able to afford such education. On the other hand, a school can follow its own curriculum or curriculum stated by the state, to provide good and low cost education.

Now, consider the case of disabled students, like children with dyslexia, children who are blind, etc. It would be a disaster if same curriculum is followed for these children. For e.g. dyslexic children wont be able to understand same course. They required special training and special curriculum is required which would cater to them. A blind kid needs education which helps him deal with day to day problems, like walking, understanding things by hands, and other aspects. Same curriculum would prove to be great disadvantage to them.

Also, a country can be divided on the basis of religion, caste, and language. Consider Tamil Nadu(T.N.) and Madhaya Pradesh(M.P.), two states of India, differing on the basis of caste and language. The state language of T.N. is Tamil where as for M.P. its Hindi. If T.M. students are taught only Hindi as per national curriculum then, they would be treated as outcast and wont be able to converse and write their own mother tongue. Similar is the case for MP students if they are taught only Hindi. One solution can be to teach both the language to the students of both the states, and whole India. But, India has 28 states, with more than 100 language being spoken. Every student can not possibly learn all the language. So State wise curriculum is required.

So, all students of a country shouldn't be taught same curriculum. The curriculum should be designed on the basis on region, religion, language, and caste. It should help students to learn their mother language, get mixed up with their society and be different for disabled children who need special curriculum.
