I had a really interesting conversation with a couple of guys a few months ago about cost of living. Cost of living is a really interesting entry point into thinking about economics, policies, wealth and such. I really think our decisions would be better if this was a bigger part of the economic debate rather then the very abstract macroeconomics, political theory and abstract ideological debates we have been carrying for so long. The role of technology, policy and taste/choices is a lot easier to decipher. I think it's a lot more productive way of structuring public debate/demands/protests.<p>Cost of living at the fat centre of the distribution for many/most households in advanced economies looks something like like this:<p><pre><code> - Housing + utilities (25-50% of income)
- Transport (10-20%)
- Groceries (7.5-15%)
</code></pre>
Housing is the big hairy item. It's dishearteningly competitive, so high income places often have correspondingly high housing costs and the percentage remains constant.<p>Anyway.. Transport.<p>Transport is a major cost item and it's quality is important. A fundamental ingredient in most people and place's fundamental economic wellbeing equation. It's also one of the most fixable with technology.<p>A 90 minutes commute on crowded public transport is way worse than a 10 minute walk or drive. Transport infrastructure takes up a lot of space, affects air quality, makes noise, affects walkability and lots of other key quality of life issues. Energy. Time. Health. Money. Transport is a very big deal.<p>If you've seen cities that had major increases in cycling and/or electric bikes/scooters, you were probably surprised by the success. There is a lot of potential here.<p>10-20 mph electric bikes, given the right customs, rules and infrastructure can be awesome in dense urban areas. Potentially game-changing over time.
