> Ok most of what you're saying make sense, but having gone to bike lanes in lower manhattan it seems like it's a lot of food delivery people

Yes, I should have mentioned that I specifically meant people using bike lanes for commutes. Bike lanes for work or for recreation are a totally different story, and I have nothing against them.

However, in this case it still reinforces my point: delivery by bike is a luxury good. It still is something that makes living in an utterly unaffordable area more bearable for people who have money.

> I suppose we'll agree to disagree on this one, there's like a bajillion books that assert the opposite so I will let those and the intertubes do the talking.

I'm actually not saying anything that is not an accepted fact in urbanism.

> As it relates to the study, I'm a little confused how it relates to the above discussion. Is this a good or bad thing to have density of jobs relate to skill level?

No, it's not good. This means that good jobs force people to move closer to the centers of their concentration. This automatically reduces opportunities for other people.
