Who is Bob Dylan talking about in "Positively 4th Street"?

Dylan said in the early 80's that when he uses "you" in a song, about half the time he's talking to himself. Dylan usually talks about a composite of people, himself, those he loves etc. I doubt its Sara, as they got married in '65. It maybe Joan Baez, it may be himself, his agent. Like most great art, the artist rarely tells you who the subject is, you're left to your own devices to interpret it.

Here's the song:

You got a lotta nerve

To say you are my friend

When I was down

You just stood there grinning

You got a lotta nerve

To say you got a helping hand to lend

You just want to be on

The side that's winning

You say I let you down

You know it's not like that

If you're so hurt

Why then don't you show it

You say you lost your faith

But that's not where it's at

You had no faith to lose

And you know it

I know the reason

That you talk behind my back

I used to be among the crowd

You're in with

Do you take me for such a fool

To think I'd make contact

With the one who tries to hide

What he don't know to begin with

You see me on the street

You always act surprised

You say, "How are you?" "Good luck"

But you don't mean it

When you know as well as me

You'd rather see me paralyzed

Why don't you just come out once

And scream it

No, I do not feel that good

When I see the heartbreaks you embrace

If I was a master thief

Perhaps I'd rob them

And now I know you're dissatisfied

With your position and your place

Don't you understand

It's not my problem

I wish that for just one time

You could stand inside my shoes

And just for that one moment

I could be you

Yes, I wish that for just one time

You could stand inside my shoes

You'd know what a drag it is

To see you
