Question

why is equality needed for all people

Answer 1

There is equal opportunity and equal ability.

It is possible for someone without a natural gift in something to work very hard to achieve the same result. Thus lets say two people want to go into engineering, person A has an IQ of 115 and person B has an IQ of 155. IQ is a measure of natural comprehension, not learned knowledge; thus it is fully possible for person A, with much more work, to have the same knowledge on a subject/field as person B.

Thus it is important as a society to allow both person A and person B a standardized level of opportunity to obtain the same result (degree in engineering in example above).
Now it is perfectly acceptable for a college (so public/private sector not government) to provide whichever person (A or B) they choose with a better scholarship offer; so long as the people (government) are providing the same basic opportunity for both.

Now looking into other social/political arguments people want to have this grandiose ideology that everyone is equal. This is because they dont want to feel like they have disadvantage to anyone else. Genetics proves DNA is not equal and different races and different family lines are not equal, just use average height as a very clear example of this. I think as a society we would be one very large step closer to evolving past our differences if we could just accept this.

Answer 2

Equality prevents any section of society from dominating others section in processes such as community capacity building . It also recognizes some people may need more support than others in order to achieve their full potential....
