It was a lot whiter for one thing. Back then it was 69% Hispanic and today it is around 85%. The 1986 amnesty accelerated that change. Today if you see white folks around town they are usually military or federal LEO associated. We actually used to have free range white girls around here, now they are mostly dependas.
We had a lot more crime back then too, but that was the whole country really. I had friends who work in convenience stores back than and they usually averaged at least one "beer run" every night, with the occasional robbery. There were lots of home burglaries which were largely committed by illegals from south of the border, the border wall fixed that. Nowadays even "beer runs" frequently make the local TV news because they are so uncommon. Our "crime of the week" this week is some kids breaking into unlocked cars. I know it doesn't meet people's expectations of there being blood on the streets here, but the facts are Dallas, Houston, Austin, and San Antonio are much more dangerous places.
Back then we also had a large garment manufacturing industry: Farah, Levi's, Lee. Those are all gone now, largely replaced by call centers. El Paso Natural Gas (later El Paso Corp, now part of Kinder Morgan) also had a large presence in the community as their corporate headquarters were here until the late 1990's and they occupied two high rise buildings downtown.
UTEP basketball was HUGE. They were one of the 10 most successful programs during the 1980's and the games largely sold out and were the place to see and be seen. They broadcast the games on the local network affiliates, even the home ones.
You could get a live in illegal Mexican maid for as little as $30 a week + room and board.
Going over to Mexico for drinks/dinner/dancing/shopping was an everyday thing.
El Paso has it's own appeal, some people get it some don't. Personally I like the weather here more than most places I've been (save maybe Southern California, but I'm not willing to put up with all that goes along with that place for lots of temperate days). The nights are cool and the days are hot and dry and that suits me. There is lots to do outdoors here: tons of hiking, offroading, skiing isn't far away, as are the mountains. It is a bit of a drive to some good fishing though. I'd also be willing to wager that the average El Pasoan gets to shoot more than folks from DFW do. We have lots of open desert, BLM land nearby in New Mexico, and a great military range that is open to the public in addition to several indoor ranges.
