Originally, I had gone and taken, I went to Irish Chicago. And I had taken the summer and took a job in Eastern Europe. The Western work crew had walked off, and I found myself as the assistant manager of a huge facility. It was like going back into the 1870s or something like that. It was horse, and the roads were meant for carts, not cars. It was a great experience, but everybody had lots of U.S. dollars. in their pocket. So all transactions were translated into US dollars and the local currency was pretty much the official exchange rate was, I think at the time, maybe 17 or 18 Zawadi per dollar, but the black market was over 100. So there's a big market and people taking you know, official US dollars and converting them at the 17 rate and then pocketing the difference if you're in government. The corruption was pretty rampant. But what it gave me the, it gave me an understanding of the dollar overhang. So in graduate school, I wrote a paper looking at the dollar overhang in fiat currency because with the Britain Woods Agreement, we had gone off gold. So there was no underlying value to the dollar other than anyone's desire to transact business with the United States. And in the past, when fiat currencies had existed before, and I think the worst example was a Portuguese discovered that the African world traded in beads and they could automate the making of beads. So they totally bankrupted Africa. And the only thing they had left to sell were slaves. So it's a It's a very kind of a strange feeling when you have a dollar that loses its foundation, then goes across. And the only value is in doing business with whoever the party is on the other side, assuming that you can buy goods at that value based on the exchange rate. So I wrote a paper looking at the interest rates, exchange rates, and local pricing and the implications of that. Because I was buying when I was in Poland. I was buying bricks from Hungary. I was going into East Germany, buying shovels and doing all this other stuff and running into all this currency. But the only value that people would actually take is dollars. So the U.S. was shipping me like $50,000 to go figure out what I needed to buy, which actually went a long way. purchasing. So I wrote that paper and it turned out that a bunch of economists at Chicago had read it and I ended up taking a job at W.R. Grace and found myself there a couple of weeks and I got a call from, and they had hired me with the idea that somehow I had some deep understanding of all their problems of exchange rates and owning assets in foreign countries, which they had a lot of and they had no idea how to account for it. They didn't, it was pretty much arbitrary. There hadn't been any rules written on how to account for foreign assets. Other than I put a dollar in, how many dollars am I getting back? It's very much like the equipment industry. It's like, I don't care about all those things. It's just, I got a dollar. How many dollars am I getting back? It was basically, I'm running with how much cash do I have in the bank at any one time? pretty oblivious to the balance sheet implications.
