Is Technology the Reason for Taking Away Middle-Class Jobs?

So, like this, with the rapid advancement of technology many middle-class jobs right from that of secretaries to travel agents jobs have started vanishing day by day. In a developed country like the United States, 70 percent of the professions at present are low-paid leaving only 29 percent of well paid jobs.
In 17 European countries nearly 7.6 million jobs have been vanished since January 2008 till last June.
So, the experts have warned as they have predicted that, in future there will be a loss of millions more jobs, if the technology starts becoming even more sophisticated and powerful, after it reaches deeply into our lives.
As the situation for the middle-class jobs are like this at present, there are few other occupations which gain lots of demand as the technology starts advancing even more. Those jobs can be included as the software engineers, app designers for smartphones, tablet computers etc. But, overall needless to say, the technology is taking away more number of jobs than the number of jobs it is producing.
