In the long run it will be very good. This same progression happened in Japan. At first the "high tech" jobs were just money work of mindlessly screwing on the same part. But then later the high tech job is the person who programs or designs or services the robots. There jobs pay more.
The bad news is that almost always the person doing the money work is not the same one to get the news robot service job as he will lack the required education.
The end result is what we see here in the US. A two class system, those with good education, four year degrees (at lest) in technical subjects making a middle class wage and others working in fast food stores who can't afford to even buy a car let alone a house, send two kids to collage and so on.
But in the long run the robots recreate tens of thousands of much better jobs while forever eliminating jobs for unskilled workers
Well, look where Japan ended up in the financial chain a public debt of 230% there GDP

- there's no country more broke then Japan, just because there economy is already stagnating since the eighties, because there workers are to expensive, they have no natural resources at all, they have to invest heavily in damage control and last but not least, the Japanese have the highest life expectancy of any demographic group in the world.
The western countries may design everything, but it's also the west that buys them. So in the end the money goes to the country that buys the least and produces the most (simple mercantilism - minimal import, maximal export - destroys the market in the long end, if everyone decides to use the same strategy - but it worked great for 15th century France). It doesn't matter how heavily you invest in education. As long as we design here and build in the developing countries we'll see a money drain. As soon as the developing countries have a decent educated base themselves, we'll end up just buying stuff.
The economical growth in western countries is mainly based on population growth, efficiency increment, inflation and debt creation.This growth is very very relative. It's not because we earn more, we become richer. The economy might have grown significantly in absolute numbers, but if you take inflation and population in account, we apparently create less value then we used to. EG. US - GDP/capita was about 5,200 in 1914 (
source). Current GDP/capita is 47,677. What is the buying power of 5,200 dollars from 1914 in comparison to today? $113,973.08 (
source) . How absurd is this? So in the end every thing ended up becoming cheaper in a way, but the actual value creation decreased! We found way after way to make the production process cheaper, and in the end we became cheaper. The relative economical growth has been negative all those years ...
So to keep our economy growing we have to keep making stuff cheaper and cheaper. We have to make it so cheap that even persons without a job (like jobless and most importantly grannies) can keep buying stuff (or better: the workers can sustain there costs). But how will we accomplice this? After the Chinese get richer, who will we turn to (what's happening right now)? What if the easy accesible sources of petrol, rare earth elements, Uranium, copper etc. run dry? Or the climat changes so much that arts of our rural areal get useless? Who honestly still expects that 'science' will be able to keep up?
And I think you have the wrong vision on what a two-class system is. Okay, in Europe, money is divided somewhat more equal, but that's all thanks to larger gouvernemental budgets (and thus higher taxes). But it hasn't been that way forever. The reason why US didn't approve national health insurance and other social securities is because you never got the extreme polarization at the end of 19th century Europe knew. 5% of the population owned 95% of the value. Although slave labor was abolished, people didn't get more then a shag per 10 headed family, some coals to heat that dump and some dry bread and potatoes which they all rented/bought from there employer. In the end they received money, but ended up paying it all back to the textile giants. That's a two class system (like most developing countries still know nowadays). In the US there's a 'gap' but it's not in anyway as big as the gap between the European worker and the textile barons, the serfs and the Russian tsar or nowadays the Chinese farmers and the Hong-Kong traders. It's kinda hypocritical to say that someone who ain't able to buy a flatscreen and the latest ipod is poor, if still a third of the world's population suffers severe famine.
