Someone just has a very different relationship with "worry". As someone who's net worth is currently a tiny fraction $2mil, I will observe that the only times I have ever worried about my finances were when my net worth was negative AND I was unemployed.
Is this irony or just staggering cluelessness? A family net worth of $2 million puts you in the top few percent.
(From http://www.federalreserve.gov/econresdata/scf/scf_2009p.htm, it's somewhere above the 95th percentile of family wealth in 2009)
