Lonesomeness is something that all humans (no matter who they are or where they live) know well. In a way, it connects us. However, the speaker of "Alone" warns that we cannot go through life all by our lonesome selves. Life will swallow us whole unless we've got family, friends, or a community of some kind to help us through the hard times.
Although "Alone" seems to worry that people are isolated, the poem itself actually breaks out of isolation by addressing other people.
There isn't any solution to the isolation described in this poem.
The speaker of "Alone" ominously declares that "the race of man is suffering/ and I can hear the moan." Instead of talking about how suffering is something that all humans experience at some point in their lives, our speaker warns people about a change she observes in the world. It's as though humans are suffering more and more. She's noticing a shift in how humans live, and she's worried.
Although the speaker suggests that being alone is the cause of suffering in this poem, the true suffering seems to come from not knowing how to nourish the soul.
This poem offers a cure for suffering: finding a community that can nourish the soul.
We know from the start of "Alone" that our speaker is struggling to find her spirituality, to feel connected to something greater than herself. She is lying in her bed thinking about how to find her soul a home. As a result of her need and quest for spirituality, she has a revelation about all people. She realizes that in order for people to find homes for their souls, they have to stick together. Community helps spirituality flourish.
There's no actual cure (in this world) for the alone-ness that the speaker describes in this poem.
The cure for the alone-ness the speaker describes can be found by re-connecting with people around us.
Lots of people feel that money can cure everything, but the speaker of "Alone" (and the Notorious B.I.G.) knows differently. She tells us that even millionaires, with more money than they can use, can't make it through life all alone. Money doesn't bring happiness and it doesn't chase the blues way, she argues. In fact, it seems to make some people even lonelier. Loneliness, therefore, is something that everyone, regardless of money or class, copes with. It's a powerful force.
As it turns out, money actually makes people less fulfilled than other, poorer people.
Money doesn't affect whether or not a person is alone at all.
