Millennials certainly think so. In its landmark 2010 survey of millennials, Pew Research found millennials in general to be an optimistic and confident bunch, even in the face of economic uncertainty. For example, even though 68 percent of millennials said they were not earning enough money to lead the kind of lives they wanted right now, a full 88 percent believed that they would earn enough in the future [source: Pew Research Center].
Key to this question, perhaps, is its wording, "Do you now earn enough money to lead the kind of life you want, or not?" The Pew survey found that the youngest generation is surprisingly old-school in its life priorities: Millennials chiefly want to be good parents, raise happy children and give back to society. How much money is "enough" to meet those admirable, but not necessarily expensive goals? That amount will likely be different for everybody.
Which brings us back to the original question: Will millennials be the first generation to do worse than their parents? While we're parsing sentences, maybe it's time to re-examine our definition of "worse." If income and personal wealth are our only metric for measuring success, there's a very good chance that millennials will fall short of the financial gains made by their parents.
But what if we follow the lead of several prominent global economists and change the success metric from Gross National Product to Gross National Happiness? When Columbia University's Earth Institute assembles its annual World Happiness Report, it considers much more than median household income, but also community trust, physical and mental health, and general life satisfaction [source: Helliwell et al.]. On that list, the United States came in 17th in 2013, slightly worse than Mexico (No. 16) and well behind our northern neighbor Canada (No. 6) [source: McCafferty]. In the Pew survey and others, millennials tend to prioritize happiness and personal satisfaction over job title and salary. Look out, Canada.
