There's no dilemma of "wages vs. technology". It's not a real problem.
Technology advances, and the economy adapts. That's how it goes. If burger robots catch on (which I doubt will happen), then I have no tears to shed for Mcdonalds cooks, just like I didn't shed tears for the employees of Borders Books, or all the wheelwrights and buggy-whip makers.
We (humans) are very good at adapting. There are millions of people working in fields that didn't exist 20 years ago.
Yes, there is a problem, and that problem is getting worse every day. This world is entering a high tech phase of man vs machine, and a large percentage of the population of this nation is ill equipped to meet that challenge.
Our education system is, and has been for fifty years or more, in serious decline compared to other industrial nations, and even some 3rd world nations. Our public schools are graduating functional illiterates, and our public universities are turning out high school graduates at a record pace. Those who are not well grounded in reading, writing, and mathematics, will not fare well in the looming high tech economy.
