Food waste and monetary ecomincs, my guy. I see kids dying of hunger and starvation in the world, women being forced to sell their bodies to feed themselves, their kids, their families. All heavily influenced and helped by fiat ponzi monetary system. The monetary system where currency can be devalued and instantly impoverish the masses, inflation constantly wiping out the value of their labour/savings. And control of it belongs to only a few elite countries in the world + the banking system.
The other major thing that gets to be in general, which is connected to both of them is oppression. Oppression leads to both of those, the tool of oppression is paper money. Oppression is what leads to what the Israelis are doing to the Palestians, the Arabs to the Yemenis, the US government to it's citizens, India to the Kashmiris, the Chinese to Uigurs and the people of Kong Kong. The US is doing to Venezuela And it's happening all across Africa, South America and the world.
You could say all this happens because power is concentrated in the hands of the elites. That power is then used to oppress and sow all the problems in the world, via several mechanisms the most important of them is the toilet paper money (that can be inflated away). Therefore, to shrink the size and power of the state, to restrict it's powers and return powers to the citizenry is the way forward.
Well I went off on one, lol. Oppression, ungratefulness, monetary economics and the small state (need of it) are what I'm quite passionate about.
