While some individuals with developmental delay (AN INVISIBLE DISABILITY AND NOT AT ALL WHAT YOU'RE PICTURING) can improve their social skills by being social, for many, their disability (NOT WHAT YOU'RE PICTURING, STOP USING YOUR IMAGINATION), is something that they were born with, is permanent, and requires outside assistance. It is not helpful to tell people with no social circle, whether due to disability, poverty, depression, or something else, that they can magically be social or become social somehow without outside assistance. You may be capable of just being social and you probably have been since the day you were born. There are a myriad of reasons why someone wouldn't have a social circle, and many of those people cannot simply "be social." That isn't how it works.
I have been trying not to say the words disability or poverty or depression because I knew your brain would shut off and you'd focus only on your own imagination and not what I'm trying to say. You'd also probably imagine that I'm talking about a small population of people.
Edit: Why don't you write a poem about paying psych workers at least $40 an hour?
