Hello

The term 401k keeps popping up in movies and Tv shows -what is this please?

Wikpedia reference will explain:

En.wikipedia.org/wiki/401(k)

In short, from a mad woman, it's a retirement saving program.

From Wiki...
In the United States of America, a 401(k) plan allows a worker to save for retirement and have the savings invested while deferring current income taxes on the saved money and earnings until withdrawal. The employee elects to have a portion of his or her wages paid directly, or "deferred," into his or her 401(k) account. This deferment is also known as a "contribution".
