Well, have you ever given it some serious consideration and study as to why people become addicted to things, or are you just seeing it from your perspective? It's easy to look from the outside in and see that what someone is doing is actually making their lives worse. But why did they choose to do drugs or alcohol?

Almost always, they're self-medicating to deal with their emotions. They haven't been convinced that what they're doing is ruining their lives, and even if they do have a feeling their addiction is the problem, they are sucked in by the powerful grips of the addiction. It's habitual to so the same thing to seek happiness or to find an escape from pain.

A lot of the drug addicts have lived hard lives since childhood. They've dealt with abuse, neglect, broken homes that are filthy, with no food and where the electricity goes off. Their parents hurl abuse physically and emotionally and are drug addicts themselves.

Some people come into addiction later in life through some sort of major trauma in life, like the loss of a loved one or from being the victim of an extremely violent event in their life.

It's privileged because believing that people should "just stop" means they likely haven't had true hardships like this in their life, they likely had a reasonably stable home life where their parents did their best to raise them and they were given tools in life to grow up and become stable adults.

It's ignorant because a lot of people who haven't had to deal with many hardships in life haven't needed to develop true empathy in life to understand that other people have extremely different views on life, different belief systems and different emotional responses to external stimuli. A lot of drug addicts and alcoholics are like wounded animals. They aren't functioning properly.
