Safety Last is interesting to me because it shows a small glimpse of life in those days. (Possible Spoliers)

I find things about it interesting, how people were paid in little envelopes, and how Harold's wage seems to be something along the lines of minimum, and how is rent is equal to almost one pay period.

I also think it's funny/fascinating that retail hasn't changed much. That 'fire sale' brings back memories of when I experienced Black Friday in retail, with the bosses patting themselves on the back while the poor workers deal with the crowds.

Fun stuff!
