It doesn't really answer any question to confront the OP's link. So your response to a guys idea of 20 hour work weeks for the country to employ every person not employed is to do something to make basic necessities cheaper?
Food, just look at the recent milk bull shite to realize that it's heavily subsidized and costs less than it actually is.
And almost everything else you noted is essentially free to large segments of the population thanks to the workers.
Do you have a comprehension problem?
I explained that I responded to the comment in the OP that we need to 'stop buying so much'. Instead, we need to cut down the cost of living, so we can buy more of what we choose, instead of having our legs cut from under us by these 'necessary' things to function.
