C'mon, they're obviously speaking for the majority but yes, as you've stated there is a minority that finds their work fun and meaningful. That is incredibly lucky and great for you!
Actually, I do like my work but I prefer to have a choice whether to work, say, 30 hours and earn slightly less or work "full time" (what a terrible choice of words) and earn the same as my colleagues. Most employers don't give me that choice and force me to work 40 hours.
