物化他人就是物化自己

I’m looking to get married to a guy who makes at least half a million a year. I know how that sounds, but keep in mind that a million a year is middle class in New York City, so I don’t think I’m overreaching at all… I am looking for MARRIAGE ONLY… I wouldn’t be searching for these kind of guys if I wasn’t able to match them – in looks, culture, sophistication, and keeping a nice home and hearth. What am I doing wrong?

I read your posting with great interest and have thought meaningfully about your dilemma. I offer the following analysis of your predicament. Firstly, I’m not wasting your time, I qualify as a guy who fits your bill; that is I make more than $500K per year. That said here’s how I see it.

Your offer, from the prospective of a guy like me, is plain and simple a cr@ppy business deal. Here’s why. Cutting through all the B.S., what you suggest is a simple trade: you bring your looks to the party and I bring my money. Fine, simple. But here’s the rub, your looks will fade and my money will likely continue into perpetuity … in fact, it is very likely that my income increases but it is an absolute certainty that you won’t be getting any more beautiful!

So, in economic terms you are a depreciating asset and I am an earning asset. Not only are you a depreciating asset, your depreciation accelerates! Let me explain, you’re 25 now and will likely stay pretty hot for the next 5 years, but less so each year. Then the fade begins in earnest. By 35 stick a fork in you!

So in Wall Street terms, we would call you a trading position, not a buy and hold … hence the rub … marriage. It doesn’t make good business sense to “buy you” (which is what you’re asking) so I’d rather lease. In case you think I’m being cruel, I would say the following. If my money were to go away, so would you, so when your beauty fades I need an out. It’s as simple as that. So a deal that makes sense is dating, not marriage.

Separately, I was taught early in my career about efficient markets. So, I wonder why a girl as “articulate, classy and spectacularly beautiful” as you has been unable to find your sugar daddy. I find it hard to believe that if you are as gorgeous as you say you are that the $500K hasn’t found you, if not only for a tryout.

By the way, you could always find a way to make your own money and then we wouldn’t need to have this difficult conversation.

With all that said, I must say you’re going about it the right way. Classic “pump and dump.”
