what is a good way for the working class (90%+ of all humans) to save
Gonna sound like a dangerous lemmy communist, but vote for parties who want to raise wages and join Union to defend your rights. The main problem is that most working class struggle to finish the month without a negative bank account, once it's solved, saving become possible again
But if their savings is in fiat, and its stated goal is loose value 2-3% annually, then the working class could never retire unless they make every economic investment choice correctly their entire life to have beaten inflation
