Ban interest and live within your means
Kill inflation and unnecessary rapacious behaviour to continually keep running while standing still.
Interest is the root of the problems. Interest is what drains ( or siphons) peoples real resources and wealth to fewer and fewer people who control the levers of wealth (bankers).
However, it does mean you need to save before you can afford to buy.
Savings will also not be eroded by inflation.
It does however require the total banning of interest. Not sure how this can be achieved easily.
