First, thank you for that truly brilliant essay. [If I may, the sentence where Keynes is referenced could use a bit of honing.]

My studies have taught me that poverty and economic instability (depressions/inflation) can be permanently eliminated with a "democratically distributed income" (which is as revolutionary as it sounds, but not radical: it can be grafted onto any existing economy).

Beyond that, I have learned that differences in income/wealth are not in themselves an injustice. Economic exploitation — wage slavery, i.e., using (employing) others as machines for one's own monetary gain — is unjust. A democratically distributed income could be expanded to end exploitation.
