If I recall correctly, Socrates taught by answering questions and encouraging new ones, not just spouting knowledge according to a set curricula, like we do today.
Socrates was unusual then and now in that he tought by asking questions encourage his students to think for themselves and discover answers on their own.
While what Khan is doing is great and praisworthy, it is not the Socratic method.
There are several good arguments for leaving the tag on ***for a limited period of time***.
(1) The tag could contain receipt information. How many times have you tried to return an item and lost the receipt?
(2) This could be used as a "gift receipt". Someone you give the clothing to could return it within a specified perioed without any paper receipt.
(3) For some product types, it could be used to store warrenty/service/product information. Imagine tagged prescription drug cases, combined with a home reader that can read out prescription details to a disabled owner.
(4) They can be used in toys. A stuffed animal with an integrated reader could detect and identify his "friends".
And many other uses.
These tags can provide signifigant savigs up to and just after the sale of products. On that alone they are justified (in a business sence) even if customers remove the tags at the time of purchase. But, they can also provide a platform for added services.
Just like you don't have to keep a paper receipt, why assume you have to keep the tag? Also, just like a paper receipt, if you loose it (or remove it) you may loose certain benefits (return/warrenty).
Generally I agree with the above. Each of the items said should be carefully considred by anyone considering moving overseas. However, I think that some of the quoted facts may be incorrect.
I am an American working abroad, and I am now living and working in my fourth country. I have had the great joy of filing (and paying) US income taxes each year. The Foreign Earned Income Exclusion (IRS Form 2555) used to be $70k, and a few years ago they started scaling it up. For the 2000 tax year, I belive the exclusion is $76k, and it will go up $2k per year until it hits $80k. The exclusion allows you to subtract that amount from your taxable foreign earned income. It is not actually a deduction, but an "exclusion".
There are several ways to qualify, so you do not have to be absent for an entire tax year. I moved overseas in an August many years ago, and was able to exclude all of my overseas income for the rest of the year. You do have to be overseas for at least a year, but the year can start any time. The amount you can exclude is the porportion of the year you spent overseas. That is, if that first year you were out of the country for 40% of the year, then you could exclude 40% of $76k from your taxes.
While the Foreign Earned Income Exclusion cannot be used for income in the US (interest, capital gaines on stocks, etc.) it does not preclude you from using the exclusion. So, you would pay taxes normally (after all deductions) on US earned income, but you can still exclude your foreign income.
Finally, you can also claim tax credits for paying income taxes to a foreign nation on foreign earned income. If you are in a high income tax jouristiction, the tax credits should be more than your US tax obbligation (on the foreign earned income) so you shouldn't owe any US taxes. However, if you are in a low income juristiction, you could end up owing US taxes if you earn more than the amount excludable.
Also, regarding contractor rates, I generally pay about 1000US to 2000US (actually 700GBP - 1500GBP in the London area) per day for the contractors I use on projects, depending on skill and level.
Concluding, the above posters comments are extreamly valuable, and should be considered by any person considering working overseas. Furthermore, make sure you actually do the research yourself and personally confirm each of the particulars, including the ones I have presented here.

However, what is often forgotten is that the data stream between keyboard/mouse and the smartcard is in the clear. A smart trojan would attack that stream, and just tell the card "the user just keyed in an order to pay www.chaos.de $20, please encrypt".
The Amex Blue readers, as well as some of the readers the my company products have a PS/2 interface on them. The reader sits between the keyboard and the computer. When entering information to the card (specifically a PIN) the reader intercepts the the signal, and it never reachers the computer, which means it is never available to a trojan.
More security than not, but there are still ways to attack that system (Tempest, video camera watching the keyboard, etc.) -- Walter Mitty wmitty at hushmail dot com
