Bitcoin fixes this.
What fixes this, is realising that debt is artificial and an economy of the future needs to realise tangible goods have more value.
Why should a country have to borrow money to provide food stamps for people? Just provide the food. Healthcare? Just provide the hospitals. I'm not advocating for communism - far from it. A distributist model of social security and healthcare is what is needed. Not some larpy digital coin that's based on speculation. Speculation is what got us into this debt mess to begin with. Speculation is not the answer.
Where does that food come from? Government run farms, hospitals? Those takes money to build and staff.
Sounds like a Magical Money Tree.
I too could be the source of my own currency (as could you, or a bank, or another business), thus would not need to borrow my currency to pay for the goods and services I desire.
As for the "what's needed" for social justice, that's your opinion. It might even be the "majority's" opinion. But what if I don't agree? Will you still impose taxation through force on me to fund your ideas?
Anyway, my best advice for you is to not hold crappy bitcoin (and/or gold/silver), and keep your wealth in US dollars (or whichever other fiat currency). I guarantee you won't regret that strategy in 2-5 years.
