Regarding videogames and TV, to some people it isn't. Videogames for some people provide such an effective escape from real life it becomes like a drug in it's short term effects.
Similar to alcohol and other substances, for some people it's ok to enjoy from time to time, for some it can ruin their life
And for some people, the same thing is done with... work. Most of us wouldn't think of it as an escape from real life, but for some people it is. Overworking and dying young from it isn't just an issue for very physically demanding jobs either.
Basically anything can become an obsession that makes everything else go away, at least for some people.
Sure but with work if you escape the cycle you are left with money and skills that are useful in real life. Games are just a temporary sedative that can lead to depression and anxiety about the real world while not providing anything truly useful. At least they are for me. I had health problems a year ago that lasted for about 4 months so I had an excuse to start playing again so instead of losing 4 months I lost 6 or 7 and then another 2 months to adjust to real life again when I realized I'm wasting my life in a video game and was becoming really depressed
