JPMorgan CEO Jamie Dimon uses his annual shareholders letter, out today, to urge companies to play a bigger role in fixing the world’s problems, Axios Closer author Courtenay Brown writes.

• Dimon says the nation's policy design and implementation have been "hampered by short-term thinking," and few institutions are blameless.
• "We are bogged down, sometimes crippling our nation, because of self-interest and the associated bureaucracy and bad thinking that follow."

Dimon told Axios in an interview: "I think America has a bright future. I don't know if we're at a crossroads or not, but I think the better strategy is to assume we are and to fix it. It's a bad idea to not fix it and hope that it really wasn't that important."

Dimon's letter — widely read for insights on the economy, the financial system and politics — dedicates an entire section to public policy:

• Dimon says America's competitiveness and leadership were challenged by "China, Covid-19 and our own competence."

On the stock market: "While equity valuations are quite high (by almost all measures, except against interest rates), historically, a multi-year booming economy could justify their current price."

On the lasting effects of remote work: "For every 100 employees, [JPMorgan] may need seats for only 60 on average. This will significantly reduce our need for real estate." But the bank is still planning to build a new New York City headquarters.

We told you last week that Gallup had found U.S. membership in houses of worship had fallen below 50% for the first time in 83 years of polling.

Axios Future editor Bryan Walsh unpacks the trend:

• Membership in houses of worship correlates with age: The oldest Americans are much more likely to be church members.
• The dropoff is particularly stark among millennials and Gen Z, who are about 30 points lower than Americans born before 1946, compared to 8 points and 16 points lower for Baby Boomers and Gen X, respectively.

What's next: Children who grow up without organized religion are less likely to worship as adults. So look for secularization to continue.
