In the 1970s oil prices were high and companies in Texas spent billions on new drilling, new pipelines, refinery upgrades, etc. The companies that did all these things needed new factory buildings, office buildings and housing. Construction workers moved to Texas. Many secondary businesses expanded. Then in 1984 oil prices went down and all the work stopped. Everyone moved out. Similar things happen in vacation towns where tourists only come in the winter or the summer.
