Sorry for referring to you as him. Bad habit.
Weddings are expensive. You're right. You have to cover the cost of your plate as well as a gift. I'm not an idiot, and understand you can't skip/avoid them. I'm listening to a lot of what you said, like how you can't go out to eat in SF spending only $30. Ike's says otherwise. Class social events. Do they have these at restaurants? I don't know I haven't started dental school yet. Maybe they do expect people with negative net worth to blow money on **** they can't afford, I just don't know and will apologize to you if that's the case, but I was under the impression that they are at the school or that if it's at a bar the school partially subsidizes the tab.
As far as birthday dinners, not everybody eats out at expensive restaurants. I associate with many people that are perfectly content to hang out and watch TV, cook something on the grill, sit around a fire, go hiking, etc. If you think that all social circles revolve around exorbitantly expensive activities, then I guess we just have different social circles. Birthday with myself or one of my friends? We all go in and split two 30's of Bud Light and play pong and listen to music.
So I give up trying to convince you that you don't need to spend money you don't have on things you don't need in order to accomplish a greater level of happiness and personal satisfaction than you'd get from engaging in such behaviors.
For what it's worth, the most successful dentists I know are humble, frugal and not materialistic. The periodontist I shadowed makes his referring GP's homemade gift baskets filled with crafts and artisan snacks, instead of the much more expensive and less thoughtful Edible Arrangement cop-out. They drive Fords, GMCs, Hondas, live in modest homes, and you would never in a million years guess how lucrative their practices are, because they're spending time taking their kids hiking, kayaking, fishing, or to the zoo.
You can build relationships and referrals by being genuine and not by digging yourself into a financial hole. Is there a "happy" medium (pun intended) between what you're suggesting and what I'm suggesting? You bet. Being sensible and frugal isn't for everyone, but neither is mindlessly blowing money just to keep up with the Joneses. I'll stick to mine and you'll stick to yours.
I give up.
