[inequality] Editorial notes and suggestions

[mmcky]

The following suggestions were made in today's reading group discussion

Suggestions for improvements

• In section 5.1.1 explanation of what inequality is and why we care about it? Perhaps we could add a graph comparing inequality with happiness? (@pgrosser1 to share link to data on reported happiness)
• review and add appropraite labels to figures x and y axis for figures
• ensure figures are captioned and numbered using mystnb metadata
• We could clarify in a comment that in Fig 5.2 income is a flow and wealth is a stock

Ideas for Additions

• add some more Lorenz curve plots (comparing between countries)
• add Lorenz Curve plots of two ends of a long time period (within country) to see how it is evolving over time
• Compare West (US, UK) with Scandinavia (more social oriented policies) over the same period (let the data talk) -- while not drawing concrete conclusions but possibilities.

@Jiarui-ZH this is captured from some of my notes. Please edit with any further suggestions you made during the reading group.

@pgrosser1 when you get the chance would you mind sending me a link to the happiness dataset you mentioned. I can then try and integrate it into my current review of the inequality lecture. Thanks.

I've just added the data into the main discussion thread, but I'll just put a link to it here as well

I've linked the data sources in the thread :)
