Church’s <a href="https://michaelochurch.wordpress.com/2012/09/09/the-3-ladder-system-of-social-class-in-the-u-s/">The 3-ladder system of social class in the U.S.</a> from 2012.</p>

<h2 id="l4---secondary-labor">L4 - Secondary Labor</h2>

<p>The “working poor” earning $10 - 20 per hour. Few skills and no leverage.</p>

<h2 id="l3---primary-labor">L3 - Primary Labor</h2>

<p>The “blue collar” or “working class” earning $20k - $60k per year. Factory work skills. But If the market for their skills collapses, 
they can fall down into L4.</p>

<h2 id="l2---high-skill-labor">L2 - High-skill Labor</h2>

<p>Plumbers, airline pilots, and electricians, some earning over $100k per year. Usually some barrier to entry in their field (unions or licensing).</p>

<h2 id="l1---labor-leadership">L1 - Labor Leadership</h2>

<p>Small business owners and landlords, earning solidly upper-middle income.</p>

<h2 id="g4---transitional-gentry">G4 - Transitional Gentry</h2>

<p>Community college students coming from L2. A 4-year degree will push them up into G3.</p>

<h2 id="g3---primary-gentry">G3 - Primary Gentry</h2>

<p>The “upper-middle class” with 4-year degrees, earning $30k - $200k per year.</p>

<h2 id="g2---high-gentry">G2 - High Gentry</h2>

<p>Graduates from elite colleges working as junior executive roles in medium-sized companies, innovative startups, management consultancies, and investment banks.
Also college professors, scientists, entrepreneurs and writers. Seek both intellectual and financial reward from their career.</p>

<h2 id="g1---cultural-influencers">G1 - Cultural Influencers</h2>

<p>Recognized as smart, knowledgeable, creative and interesting. TV hosts, bloggers, journalists earning $100k - $1M per year.</p>

<h2 id="e4---strivers">E4 - Strivers</h2>

<p>Junior investment bankers, law firm associates, and young startup entrepreneurs trying to transition up to E3.</p>

<h2 id="e3---elite-servants">E3 - Elite Servants</h2>

<p>The “working rich”, law-firm partners, senior investment bankers, politicians and chief executives earning $200k - $5M per year.</p>

<h2 id="e2---national-elites">E2 - National Elites</h2>

<p>The “upper class” or “old money”. Believe that paid full-time work is dishonorable. They hold board positions and associate their names 
with institutions without getting too involved.</p>

<h2 id="e1---global-elite">E1 - Global Elite</h2>

<p>The very rich, extremely powerful and trans-national. The corporate billionaires, drug kingpins, third-world despots and real estate magnates. 
They don’t care about culture or morals, only control on a global scale. Hitler, Stalin, Henry Kissinger, Osama bin Laden.</p>

<blockquote>
  <p>What’s most shocking is always how much the doctors and even internal employees internalize the FDA mentality that you’d let 10,000 people die from approval delays vs one person go to the hospital from an unintended side effect.</p>
</blockquote>

<p>First thought: This the trolley problem. Do I throw the train track switch to save the 10,000 people on track one and send the train down track two to kill 1 person?  Many people are okay with not throwing the switch. They don’t want to be responsible for actively killing 1 person.</p>

<p>Second thought: No, this isn’t the standard trolley problem. This is really someone with a big gun standing at the track switch to keep anyone from throwing it.</p>

<p>Third thought: No, it’s not that either.  It’s 10,000 people on track one with a 100% chance of being killed. And some of them want to move over to over to track two where they only have a 1% chance of being killed.  And the FDA has built a fence to keep everyone on track one. And they have guards that patrol the fence with guns.  Yeah, that’s the FDA.</p>]]></content><author><name></name></author><summary type="html"><![CDATA[Interesting comment by Fallon at https://astralcodexten.substack.com/p/adumbrations-of-aducanumab/comments#comment-2538655]]></summary></entry></feed>
