Financially, no I don't think we...people in general...are better off (I'm 40). Some individuals definitely are, but if you compare the average high-school graduate age 30 today, to the average high-school graduate aged 30 of some years ago; or the same with college grad, etc, I think we're worse off financially than the generation before us.
For instance, my dad and his brothers all had high school diplomas and worked as blue collar workers for places like GM, Quaker Oats, etc. They had good paying union jobs, benefits, vacation, good health insurance, and retirement (real retirement, paid for by the company or union, not "save it yourself" types of accounts), and most of them worked for the same companies for decades. They could afford much nicer homes than their parents' generation, a couple of late-model cars, yearly vacations, they have very comfortable retirements. Those type of jobs are very rare now, if you can find them at all.
I have friends who went to college and grad school in the 60's and 70's, and they all say they could work full-time at some average job in the summer, and that would pay all their tuition and expenses for the school year, as well as living expenses while they were working in the summer. Now all the students I know who are paying their own way through school work in the summer, have part-time jobs during the school year, and still have to take out student loans to have enough to pay tuition and living expenses. They are starting out in the hole financially.
Cost of living has gone up, real wages have gone down, benefits have gone down, companies have zero loyalty towards employees, and as a result employees have no loyalty towards companies.
In other ways I think we're better off, I'm glad I live now, but we're definitely worse off financially.
