Actively engage in politics and realize the problem will take decades to incrementally solve, while taking tactical action in your life to protect yourself from current state. What the latter looks like is a broad conversation depending on what your potential trajectories are, what you're optimizing for, and what you're defending against.

Put the metaphorical oxygen mask on yourself first before you try to help others, and then, if you so choose and are able, defend and empower others as your sphere of influence (a function of time and resources itself) grows. Defend and empower the human, broadly speaking.
