> Thinking back I do not know anyone in my neighborhood who was genuinely a hard working person with no vices.

You're mistaking correlation for causation, which many do and is why this debate is so polarizing. Many people develop vices because they are neglected, as a coping mechanism/self-medication for their hopelessness. With more resources, they have more opportunity and don't need to self-medicate as much. This effect has been studied.
