What is the "abundance agenda" and how does it relate to supply-side liberalism?

In a nutshell the idea is that for too long, American governments (state/local/federal) have enacted regulations that have, inadvertently or not, driven up the prices of key goods and services by strangling supply and subsidizing demand. Abundance Liberals are against this combination. Namely, they want to stop strangling supply and allow for the markets — aided by the state where effective**** — to build mass amounts (abundance) of the goods and services we want and need, driving down prices.

I consider myself a Liberal of this school.

The Abundant answer to this crisis is to create “abundant” housing, of all types, where it is most needed, thereby alleviating the Housing Crisis, which to Abundant Liberals is a crisis of artificial scarcity due to government policy.

***I use the term “Card-carrying Liberal” to denote self-described Liberals who are active in expressly Liberal spaces, fighting for expressly Liberal goals, rather than as a catch-all term for “Democrat”

Abundant Liberals reject the idea that capitalism itself is to blame for the Housing Crisis, or most other economic crises we are seeing today, instead arguing that bad policy is the root cause.

Abundance Agenda and “Supply-Side Liberalism/Progressivism” are the same thing, but the former sounds way cooler.

Why do some people refuse to explain their actions or behavior when asked? Why do they claim to not know the reason instead of providing an explanation?

Why is it rare for someone to despise both the Democrats and Republicans?

Abundant Liberals want to create mass abundance in all spheres. Energy, education, housing, food, transit, etc etc etc. They tend to be deeply urbanist and aim to have “tall cities” if you’re familiar with the term in strategy games. Lots of apartments, lots of transit and walkability, and so on.
