不准确，Get a life在中文是振作点的意思。而找点生计吧means you need to find a job to make a living.I think 生计 can be used in both political articles and oral Chinese.

找点生计吧 we mean that “get a job” ，but we actually say "找点事做吧”。 "生计" is only used in some political article or news , not in oral communication。

It depends on contexts
