There are so many assumptions packed within this. You're saying because you, in the capitalist world, didn't want to train for medical research at age 18, job roles, in a socialist world, that are require less scientific knowledge should have workers that are weaker and poorer than others in different roles. What choices you made are irrelevant
Why should the cleaners in the street not get their fare share - their labour helps make the medical researcher just as much as the .
What's to say in the future once society is reordered people will value medical research in the same fashion, perhaps people will use what medicines there are but no longer seek new ways to ward off the effects of old age, or perhaps attitudes to children will change - who knows.
Being blunt, your model is wedded to status quo individualism - it's a plan that seems made by a coven of economists and other professionals and so exults wage differentials for the good of humanity.
In the real world of social organisation, when the military are attacking you from all sides, everyone being equal is much simpler
Who do they help though? Who in the here and now?

because 'revolution' is never going to be as you describe, people will have to stick together not worry about 'immigrants', whose children are whose, about who did what for whom. They won't, if they want to win, divide themselves into people who will earn a quarter of what others do - as a way to attract new support when under attack.
