A person who is in a golden nest would not have freedom. They are living under someone's/others' command, although they live with privileges.
What is the English expression of golden nest? I am translating directly from my native language.
Could it be referenced to golden handcuffs as a metaphor?
I think you are referring to the metaphors: golden cage or gilded cage. Something that symbolizes material wealth but causes limited movement. Luxurious living but no freedom.
Golden handcuffs is related to good compensation and benefits for a job, which makes it difficult for an employee to transfer to another work/company. (retention)
You may want to add the source where you encountered the term, so we may be able to give a better answer.
