Tiffany (Darwish), the pop singer of the late 1980s (who was 17 in July, 1989)? You have got to be kidding me!
I remember how, in 1989, the interest rate on my money market savings account dropped like a rock throughout 1989. The bank printed it on the bottom of the monthly statement every month. I recall it was north of 7% early in the year before falling bigtime to under 2% by the end of the year. This helped nudge me toward investing my surplus money (which I didn't have much of in most of 1989) elsewhere in 1990, starting with muni bond funds to avoid income taxes (which were much higher back then).
