I think the incredible stock market gains and home price growth over the past few years have helped a lot of people feel confident leaving their jobs for a sabbatical that otherwise might not. I know in my own case, even if a lot of the nominal growth is due to devaluation of the dollar, seeing a 7 figure balance on my net worth statement for the first time has definitely put swagger into my step over the last year or so. I haven't quit yet, but I wouldn't hesitate if something changed and I stopped enjoying my job.
