Judging by the timeline, it seemed like initial low rates had more to do with it being a new system, and less to do with some kind if "we will only do this to the rich" promise.
Also, they tried implementing income taxes previously, had it struck down by supreme court, then all the states got together to pass an amendment to allow income taxes. So, it was a pretty strongly supported change.
Honestly, I can get on board with "government tends to only grow in scope" point of view, I just don't think income taxes illustrate that point at all.
