In your world, people in wheelchairs would be housebound. But I guess we shouldn't accommodate them by requiring wheelchair ramps or curb cut-outs. They are lesser than us.
The world is not what you or me want is what you can convince enough people to do. In the country were I choose to pay taxes, people in wheelchairs are well accommodated.
But you know what that also means? That the same resources used for the ramps are not used to help someone that maybe starves to death somewhere else. I can't say I know which of the two I would choose, but I will not imply that the ones making a choice think "some are lesser than us".
Probably you will say "we can do both", "why choose", or something similar. But practically, all resources I know seem to be finite (time, energy, people). If you have infinite resources that I am not aware of, please fix all the problems.
