- Ad Astra for Real
Planetary Radio is the most hopeful, and the most humane, place on the internet. Every episode gives us a chance to feel connected, included, and welcomed, whoever we may be or wherever we may be coming from. Every episode gives us a chance to experience awe. This is what it means to be one human family, headed inexorably Ad Astra. I am so grateful for the weekly reminder of what we can be when we're at our best and doing great things together <3

Casey begs for the listeners to become a member and donate to them on one hand, while he promotes billionaires’ business ventures on another hand.

But that doesn’t stop this podcast from begging for more donations from regular people. Somehow the rich keep getting richer while the rest of us keep getting screwed.
