The equality of people is not a goal, but a correct premise. If you start from the premise that people are not equal because they are not the same, then you are already wrong in the first place (because this is a fucking racism).
That is, first a Bolshevik and now a racist for explaining to you what a tautology is. I'm growing my ignore list lately and you just ran for office.
...scientific and technological progress, it is quite possible to make sure that there are no poor people.
Precisely today there are fewer poor people than ever before thanks to societies that provide equal opportunities.
I don't blame you for anything. I'm just saying that confusing equality with sameness is a very common mistake, and there is no tautology here, people are equal, but they are not the same. And there is no need to fight for equality, because it is already there from the very beginning, it is necessary to fight against manifestations of inequality (racism, nazism and other remnants of caste systems). But in order to fight correctly, you need to clearly understand the difference between equality and sameness, because otherwise you will fight not with manifestations of inequality, but with manifestations of human individuality.
