This question reminds me of John Rawls with his work 'A Theory of Justice'. He came up with the two principles: 'each person is to have an equal right to the most extensive scheme of equal basic liberties compatible with a similar scheme of liberties for others' and 'Social and economic inequalities are to be arranged so that: a) they are to be of the greatest benefit to the least-advantaged members of society (the difference principle). b) offices and positions must be open to everyone under conditions of fair equality of opportunity' In other words: people are not created equal by nature! And if we come up with standard opportunities and laws which apply to everyone, then there will always be people in advantage or in disadvantage. So in order to overcome this gap, but still keep people in responsibility for their own lifes, opportunities and laws have to be modified to the degree of fair equality.
