Can we afford to give every child in America a laptop?
at the TechLearning blog
A few back-of-the-envelope
calculationshere (estimating conservatively when in doubt)...
A. Number of students and teachers
millionpublic school students
millionpublic school teachers (full-time)
millionteachers and students
B. Cost per laptop (a regular laptop, not the OLPC laptop)
$1,993 average district cost per client computer per year [from the three One-to-One CoSN Total
Cost Per Ownership (TCO) Case Studies]
1.5 (I'm adding 50% just to
err on the safe side)
$2,990 average district cost per client computer
per year (let's call it $3,000)
C. Total cost to give every student and teacher a laptop
53.3 million teachers and students (see A above)
district cost per client computer per year (see B above)
(let's call it $160 billion)
D. Gross domestic product (GDP)
$13 trillion (United States GDP, overall)
(percentage of United States
GDP spent on K-12 education)
$442 billion (amount
in United States spent on K-12 education)
E. Percentage of GDP
$160 billion (see C above)
$442 billion (see D above)
36% of the overall United States K-12 education expense to
give every teacher and student a regular laptop
$160 billion (see C above)
$13 trillion (see D above)
1.2% of the overall United States GDP to give every teacher
and student a regular laptop
Obviously this is very rough, but hopefully it's also thought-provoking. It
is highly possible that my numbers are incorrect somewhere. If you think I left
something out or miscalculated, let me know. Also, of course, opportunities for
savings abound (e.g., open source software, bulk discounts, buying OLPC laptops
instead of regular ones) and those would have to be factored in as well.

In his final years, Martin Luther King, Jr. become increasingly focused on the problem of poverty in America.
- Despite being widely known for his leadership role in the American civil rights movement, Martin Luther King, Jr. also played a central role in organizing the Poor People's Campaign of 1968.
- The campaign was one of the first to demand a guaranteed income for all poor families in America.
- Today, the idea of a universal basic income is increasingly popular, and King's arguments in support of the policy still make a good case some 50 years later.
10 of the most sandbagging, red-herring, and effective logical fallacies.
- Many an otherwise-worthwhile argument has been derailed by logical fallacies.
- Sometimes these fallacies are deliberate tricks, and sometimes just bad reasoning.
- Avoiding these traps makes disgreeing so much better.
For Damien Echols, tattoos are part of his existential armor.
- In prison Damien Echols was known by his number SK931, not his name, and had his hair sheared off. Stripped of his identity, the only thing he had left was his skin.
- This is why he began tattooing things that are meaningful to him — to carry a "suit of armor" made up the images of the people and objects that have significance to him, from his friends to talismans.
- Echols believes that all places are imbued with divinity: "If you interact with New York City as if there's an intelligence behind... then it will behave towards you the same way."
