I agree that the ultimate solution is a change at the level of consciousness (individual and collective) from which language (and all culture) flows.
Meanwhile, though, if I may, I submit that what we need is an advance in our understanding of justice: it has to be obvious by now to anyone with a brain that endless repetition of the Liberal incantations, 'liberty and equality'; 'equality and liberty', is not going to get us one nanometer closer to a just society.
We simply have to understand that the ethic of justice is mutual respect (of a basic kind: taking one another into account as human beings living our separate lives together in this world). That boils down to a handful of absolute prohibitions: no killing, harming, coercing, stealing, or manipulating (lying, cheating, etc.) to get what we want: so, no 'moral relativism' here.
A society governed by mutual respect would have the maximum liberty that co-existing human beings can share and a democratic political process. The "democratic distributive principle" would be applied to the economy via a "democratically distributed income" (DDI), with astonishing results for society: no unemployment, poverty, taxes, or public debt and increased sustainability (all at no cost to anyone, without redistributing anything or imposing any arbitrary limit on income/wealth). [With mutual respect as the ethic of justice arbitrariness is injustice.] The DDI could be expanded to eliminate exploitation — still without arbitrarily limiting income/wealth.
All of those outcomes would result from a change to the economic system, not changing people: that will take lots more time--but recognizing mutual respect as the ethic of justice would do much to further that process.
