it seems like differences in worldview stem from a disregard of the universal ethical principle
and it makes sense then that common ground cannot be found when opposing viewpoints are rooted in incompatible principles.
That's a very normative and idealist worldview, that itself fails to regard other, opposing principles and thus doesn't live up to the standards it pretends to set. In reality, differences in worldview often have material reasons rather than ideological ones. For example all the brilliant dialectics of Hegel ultimately amount to him embracing the Prussian monarchy as the ultimate end result of history. The final goal of all human morality. It just so happens, that he was a privileged intellectual, comfortably living under Prussian rule.
Many plastics (thermoplastics) would actually be recyclable, if they didn't put so many additives in, like for UV resistance. But then the color would get a slightly yellow tint after some years of exposure to sunlight. And who would want that? /s
