Young people are likely to have parents that were born in the '80s or just before. It makes sense that parents would want to share things from their childhood with their own children and so many people have been introduced to '80s pop culture from a young age. If they become interested in it themselves, then this interest will continue to grow as they get older.
The 1980s was one of the first times when people felt that they could really improve their situation in life. People were making their fortune on the stock market and big businesses were setting up all over the place. Places where people could spend some of the money that they had made also began to become more common. Las Vegas underwent major development in the 1980s and casinos really became popular. This popularity still remains today and people also have the opportunity to play at Vegas Palms casino online if they cannot get to a real one. People also began to take holidays further afield and long haul air travel really took off in this decade.
The 1980s were a time when everyone was free to be themselves and this is something that people want no matter what decade they were born in. People began to realize that not everyone was the same and that being a bit different was actually okay. Everything about the '80s seems quirky and strange to people who did not experience it first hand but this is not necessarily a bad thing, and the popularity of the '80s more than 30 years later shows how great an appeal it still has.
