-Indeed average copywriter annual pay [0] is $54,998 USD, versus a staff scientist's [1] at $69,091 USD
-BLS median copywriter pay for 2021 [2] was $69,510 USD, versus a medical scientist's [3] at $95,310 USD
I'm surprised that the median annual salary difference is only roughly $15,000 to $25,000 USD in favor of working as a scientist, considering the additional years doing a Master's/PhD, whereas copywriter jobs often don't need even a Bachelor's. In addition, I would've guessed that the median copywriter salary would have been far lower, as my perception was that there is a far greater supply of candidates for copywriter jobs than scientist jobs in the US (maybe this is offset by fewer scientist positions?). Alternatively, maybe the numbers are missing important contextual information in some way.
