Now People tend to give birth to children they can't Carter for, they will give birth to 8,9 children plus and they will be unable to give them a formal education, when they have grown up and they find it difficult to get a decent job, they will now be engaging in crimes of different types just to make a living.
Their is a particular tribe in my country that gives birth to a lot of children believing that the higher numbers will make them wealthy, because when the child has grown up to 4,5 year old they will send them out for begging, then be expecting returns from that child. But now due to how inflation and lack of better jobs are high in the society now, people hardly give out like before, and those children since they didn't have a formal education when they have grown, they will now be a nuisance in the society and engage in crimes just for survival.
It is not very common to have 8 kids in 2023 and to my knowledge, it all happened in the good old days you are talking about which is a couple of generations earlier. And if there is a particular tribe doing doesn't mean that is the same everywhere.
And I want to tell you that crime exists every time and probably you feel it is rising because it comes to our knowledge no matter where it happens but in the good old days, you are talking when there is no internet, no sharing of news by people so we only see what media want us to see.
Crime has always been with us. There's really nothing good about the old days. Even the people who lived in those days still complained about crime.
Moreso, crime can be attributed to a lot of reasons, it may appear to be rampant these days because the society is losing, or has completely lost value. People celebrate criminality these days.
