Can you give a "living" to someone? [migrated]

No, "a living" in this usage is pretty much limited to monetary income. As in "I don't really care for my job but it is at least a living."

If you read some classics from the UK you'll see another meaning of living -- it's kind of a job for life in the church. At least that's what I figured out from the context. I suppose a comprehensive UK dictionary would include that meaning.

Your phrase "good life" can be useful. Example: (widow reflecting on her late husband's character) He was a bit of a skirt chaser when he was younger, but he settled down after 40 and I have to say he gave me a good life. Except that isn't limited to the financial aspect. For pure finances, you could say, He worked hard and supported me well all these years.
