As one involved in conservation and biological science,  I'm aware that both groups , and most between, are contending for ingroup resource dominance; none are interested in long-term issues.

"progressives" are not in fact at all allied with conservation or submaximal populations, seeking distribution only among ever-growing humanity, ignoring environmental signals that we have already long overshot the entire earth's carrying capacity ofr our kind.

"conservatives" look toward gravely mistaken illusions like unfettered human greed establishing stability through competition. In reality retention of social power requires eliminating all but positive feedbacks, entrenching that dominance. Thus the rise of media agricultural, and marketing conglomerates, pretty much enslaving the vast majority to subservience. Emergent eusocial structures compete only by adding to the ecological overshoot.

Both dead ends, within your lifetime. Emergence and signaling (biological terms) are accelerating
