No. Having a narcissist in the family business will mean that other family members will work hard and do as good a job as they can, taking up the slack for the narc's lazy useless ass. Meanwhile the narcissist will be busy bragging about their "self-made" successful business on social media, or delivering a tedious monologue to the customers about how hard the narc works, and how the company would go under without their expertise.
The narc will tell everyone that s/he is the brains and the money and the talent and the experience behind all the company’s success, and that the other family members are incompetent fools who would run it into the ground if King/Queen/President/CEO/CFO Narcy wasn’t there to do everything and fix everything and tell everyone else how to do their jobs. They actually believe that load of horses*it, too.
They will tell the customers and their social media followers that they are the best, smartest, most experienced, hardworking, & talented person in the world and put on a good show of it, but the reality is that they are lazy, useless leeches. And to top it all off, they’re probably dipping into the petty cash and business accounts and spending it on themselves & their bad habits, too.
Do NOT go into business with a narcissist family member. Be very careful, in general, doing anything that mixes money and family.======================
