Yes, governments don’t know what to do.
However, they could deliver a very decent universal income–without having to borrow!–to carry people and business through the terrible deflationary period. It would not be inflationary during a depression.
Then, gradually reduce income and sales taxes, and institute a land rental system, in the broader sense of ‘land’–i.e. all natural resources–as Fred Harrison mentions.
That would get real wealth production happening again, and end the speculative activity in assets that is bringing world economies to their knees.
Too simple? You bet!
