Getting a job is not possible for everyone, not everyone has family or [friends] to help them and sometimes they will make the bad situations even worse them. If you've ever really needed money and were very desperate, than you probably know that people would let you starve to death rather than give you $5.
It's weird how people won't toss out just a few dollars to help someone in need, yet they'll spend $10000 or more on their pet that has an average life span of under 5 years.
But then again, if you give the person in need money, they'll keep coming back for it. It's a real crap shoot
In my own opinion, there are many different reasons why people tend to scam other people. One example is, they are in need of money. They cant get a job or they cant earn a decent amount of bitcoin thats why the only way for them to earn money fast is by fooling or scamming other people. Another reason is that, they are good in making fake websites and investments that scam people's money. It serves as their work and they are also the boss. Those people will not become successful in the future because they are earning money in a wrong and illegal way.
