We _do_ live in abundance, compared to 100 or even 50 years ago. Our standard of living has increased immensely thanks to increased productivity (from automation, computerization, etc.). As an economy we've converted this extra productivity into more/better goods and services, instead of extra time.
Oh, and before you suggest that median 1950 US citizen had a higher SoL than median 2010 citizen... taken quantifiably, SoL includes things like the size of your TV, car, access to medical care (1950 US medical care is worse than 2010 rural Indian medical care), cost of services like travel (inflation-adjusted plane tickets are like 10% the price of what they once were even 35 years ago), etc.
Technology will not take our jobs, technology will increase our standard of living in the future just as it has done throughout all recorded history. The thing is, absolute gains in personal wealth/GDP/SoL don't actually make us happier. It's an unfortunate quirk of human psychology - our absolute wealth doesn't make us happy, our relative wealth is what makes us happy. Because people tend to live around people who are about their wealth level, this means no one is very happy. (Another unfortunate quirk of human psychology - we tend to compare ourselves with people just above us wealth-wise, and assume there are more of them than we think.)
So, now that we are self-aware about our psychological quirks, here is my 3-step plan to lasting happiness
a) Recognize that on an absolute level, we are wealthier in every measurable way than before. Your TV is bigger and sharper than your grandparent's TV. You have access to lifesaving technologies, with new being developed every day. You have the freaking INTERNET for chrissakes. Now of course, _everybody_ around you also has these things... but now you are lapsing into thinking about *relative* wealth, not absolute wealth.
b) When it comes to relative wealth, start hanging out with people poorer than you. It'll make you feel rich.
c) Support some redistributive economic interventions, because more even distributions of wealth lead to more happiness that highly stratified wealth distributions. These policies will reduce our future growth of wealth as an economy, but as long as we are careful not to take it too far, it doesn't matter. Remember - relative wealth makes us happier than absolute wealth, so even if pure pro-growth policies do make us all much wealthier than the alternative, it will actually make us more unhappy if it serves to stratify the economy,
