I think this makes sense in a society where the overwhelming majority of people are mercenaries. There is something romantic about the idea of working tirelessly when you are building something to pass on to the next generation (the family farm, or ranch, or family business). It seems a lot less romantic when it is sitting in a cubicle for endless hours for a megacorp with 100,000 other cogs in the machine to earn a bunch of fiat so you can buy a house and a car and put some money away for retirement and your epitaph reads "He worked for Dupont optimizing packaging costs for 50 years."
