The pool of idle and unwanted labor will likely increase until the assumptions underlying the industrial revolution are questioned. Great public works of art and architecture are scarcely being erected today as their mere existence is seen to be "inefficient". Efficiency is a means rather than an end.
From Tawney's "Acquisitive Society":
"Such societies may be called Acquisitive Societies, because their whole tendency and interest and preoccupation is to promote the acquisition of wealth. The {30} appeal of this conception must be powerful, for it has laid the whole modern world under its spell. Since England first revealed the possibilities of industrialism, it has gone from strength to strength, and as industrial civilization invades countries hitherto remote from it, as Russia and Japan and India and China are drawn into its orbit, each decade sees a fresh extension of its influence. The secret of its triumph is obvious. It is an invitation to men to use the powers with which they have been endowed by nature or society, by skill or energy or relentless egotism or mere good fortune, without inquiring whether there is any principle by which their exercise should be limited. It assumes the social organization which determines the opportunities which different classes shall in fact possess, and concentrates attention upon the right of those who possess or can acquire power to make the fullest use of it for their own self-advancement. By fixing men's minds, not upon the discharge of social obligations, which restricts their energy, because it defines the goal to which it should be directed, but upon the exercise of the right to pursue their own self-interest, it offers unlimited scope for the acquisition of riches, and therefore gives free play to one of the most powerful of human instincts. To the strong it promises unfettered freedom for the exercise of their strength; to the weak the hope that they too one day may be strong. Before the eyes of both it suspends a golden prize, which not all can attain, but for which each may strive, the enchanting vision of infinite expansion. It assures men that there are no ends other {31} than their ends, no law other than their desires, no limit other than that which they think advisable. Thus it makes the individual the center of his own universe, and dissolves moral principles into a choice of expediences. And it immensely simplifies the problems of social life in complex communities. For it relieves them of the necessity of discriminating between different types of economic activity and different sources of wealth, between enterprise and avarice, energy and unscrupulous greed, property which is legitimate and property which is theft, the just enjoyment of the fruits of labor and the idle parasitism of birth or fortune, because it treats all economic activities as standing upon the same level, and suggests that excess or defect, waste or superfluity, require no conscious effort of the social will to avert them, but are corrected almost automatically by the mechanical play of economic forces.
"Under the impulse of such ideas men do not become religious or wise or artistic; for religion and wisdom and art imply the acceptance of limitations. But they become powerful and rich. They inherit the earth and change the face of nature, if they do not possess their own souls; and they have that appearance of freedom which consists in the absence of obstacles between opportunities for self-advancement and those whom birth or wealth or talent or good fortune has placed in a position to seize them. It is not difficult either for individuals or for societies to achieve their object, if that object be sufficiently limited and immediate, and if they are not distracted from its pursuit by other considerations. The temper which dedicates itself to the cultivation of opportunities, and leaves obligations to take care of themselves, is set upon an object which is at once simple and practicable. The eighteenth century defined it. The twentieth century has very largely attained it. Or, if it has not attained it, it has at least grasped the possibilities of its attainment."
I don't know why I'm responding to such a poorly phrased question, but interpreting it in the most charitable light: The unemployment graph I linked to is clear evidence that previous automation has not "automated away humans".
I have and found that one man could comfortably support a family of five on a 40-hour-a-week factory worker salary. Such niceties began to fade in the 70s and 80s, though, as the world progressed.
Now, do your part and honestly evaluate the world around you. Keep in mind that the appeal to progress is just as much of a fallacy as the appeal to tradition. Tomorrow is not inevitably better than yesterday.
That's news to me: So when the man's wife needed an MRI, his salary could cover this back in the 70s? He was able to buy a car with airbags using his salary? He was able to give his wife a cell phone in the 70s that she could use in an emergency? He was able to buy himself a carbon monoxide detector for his house? If he got testicular cancer, he would live more than a year with his salary? etc. etc.
Once open spaces are now subdivided, health care motivated by usury, and wages lie stagnant since the seventies. Water crises, hemispheric pollution, and thermonuclear warheads, all are modern innovations which the prewar generations would be thankful to escape.
The present isn't inevitably better than the past. The future will not necessarily be rosier.
