what you have failed to recognize is that substance abuse, addiction, etc. is not always a result of negative circumstances. plenty of folks out there who were born and raised in nice homes, by good parents, received plenty of privileges, but went astray and became lowlife heroin addicts, alcoholics, etc.. kids who grew up into self-entitled adults. born with silver spoons in their mouths.  nobody gifted me anything, nor handed me the "tools" to do what had to be done. whatever the case may be, privileged youth or broken home, you man up (or woman up), and do what's right. some grossly negligent subhuman heroin addict "parent" may be able to turn it around, who knows? maybe revert back to being a decent human being, and not a strain on society, and worse- a deadbeat "parent." for the sake of these addict's children, i would hope that they'd be able to get their shit together. until then,they don't deserve any compassion. 

you're pretty hostile, dude. 3 deep breaths. 

simmer down.
