There’s enough love to go around
The Intensifier “enough” expresses that there’s the right amount of something. When there’s enough, there’s not too much and not too little.
For instance, you’re at a cafe and a waitress says to you,
“Is there enough cream in your coffee?”
She isn’t asking if there is cream in your coffee, she knows there is. The waitress wants to know if there is the right amount of cream in your coffee. The Intensifier “enough” seeks to find out if something is just right.

With this in mind, you may hear a native speaker saying:
“There’s enough love to go around.”
By using the Intensifier “enough,” the speaker is telling the listener that people are good by nature.
