I'm interested, do you think that what the 'advantaged class' have to say is less significant than some other class? Why? It's a subject I think about often and am interested to hear any thoughts that you might have.
In my response, I said that no, I don't think the advantaged class objectively have less significant things to say. But we've already had our say, haven't we? I believe the advantaged class have consistently - throughout history - said the vast majority of what has been said. So much so, that their voices (our voices) leave little (if any) space for the voices of the marginalized to find resonance.
And yet I continue speaking... but I actively try to listen and to understand voices from angles and positions I don't inhabit... does that justify me?
Meanwhile, as I have mentioned, I also put a lot of stock in Gustavo Gutiérrez's "option for the poor." Christ demonstrated firsthand God's preference for the poor, the sick, the marginalized and outcast. That is where Jesus spent his time and self-identified. It's where he blessed, and was blessed. That would lead me to assume that God might care less about the voices of the privileged and powerful. I'd guess that's not because their voices are unimportant, but because their voices are ubiquitous, and generally align with principalities and powers that oppress, rather than liberate.
There is another voice, another vantage, that is free enough (not bought or owned) to speak the truth of God's Kingdom to a world that is inherently bought and owned.
We need liberation from ourselves. As a privileged class, that liberation comes through voices outside our own echo chamber.
