Rousseau's "Cure"

According to Rousseau, we as a society suffer from many 'ills' that were brought about by ourselves. Such ills originate from the extreme passions and excesses that arose from modern society. "Excessive idleness among some, excessive labor among others' the ease with which we arouse and satisfy our appetites and our sensuality;the overly refined foods of the wealthy, which nourish them with irritating juices and overwhelm them with indigestion; the bad food of the poor, who most of the time do not have even that, and who, for want of food, are inclined to stuff their stomachs greedily whenever possible; staying up until all hours, excesses of all kinds, immoderate outbursts of every passion, bouts of fatigue and mental exhaustion; countless sorrows and afflictions which are felt in all levels of society and which perpetually gnaw away at souls: these are the fatal proofs that most of our ills are of our own making, and that we could have avoided nearly all of them by preserving the simple, regular and solitary lifestyle prescribed by nature" (383). 

Essentially, the "cure" to the ills of modern society is through self-preservation. These ills are apparent in our own modern society as there are many who cannot afford good, natural food and there are many who are lost in our own consumerist and liquid modern world. Do you agree with Rousseau's cure? Why or why not?
