That's the whole point...they aren't really getting them cheaper.
Speaking from personal experience, I graduated from a US university a few years ago and applied for a job at various tech companies, including Microsoft. I was competing with everybody else who had graduated, and would be paid the same as any entry level developer (which was about 65k at the time).
The only difference was that, as a foreign national, if they decided to hire me, they would have to provide me with an H-1B visa.
A large number of the H-1B professionals who work for MS and Intel and other tech companies, have come in the same way, by competing against other qualified candidates, including Americans, for the same salary, and proving themselves to be the best candidate.
There is a big difference between them and the "sweatshop" candidates being brought in by the outsourcing companies.
Except that most of Asimov's robot stories were actually about the fact that the 3 Laws were simplistic and impractical, and that sufficiently developed robots would look to bend or break the laws eventually.
The Prime Directive had its own problems as well.
The point is that it is not easy to define a universal set of rules that would apply in all situations.
David Prowse, the 74-year-old actor who has enjoyed a long and varied career filled with roles such as Darth Vader (Star Wars Episodes IV, V, and VI)
Does anyone else find it funny that the example given for his long and varied career is that he played Darth Vader in 3 different movies?
Freedom is valued in India, but the concept of absolute freedom of speech is not as ingrained in the culture as it is in some western countries.
The general rise in Hindu nationalism is a recent thing, and has come from certain political leaders exploiting the discontentment among the poor and unemployed. Because India has a fair amount of affirmative action for minority communities, the Hindus are incited into believing that everyone else is being favoured apart from them, and that freedom of speech means people can do and say anything against their culture and religion.
The problem with free speech is that of course anyone has the right to say anything they like, and it requires a certain level of education to understand that that's not a bad thing.
The problem is that in practise, landmines are never a clean solution.
No matter how many wanrnings you put up, invariably some children or animals will wander into the area and get blown up, or crippled for life.
There are lots of more humane ways to implement a barrier than landmines.
Due to Farmvilles massive spamming, and my inability to make it stop telling me when my sisters/friends/coworkers have found a new cow, I've actually resorted to unfriending people who are farmville addicts. My "newsfeed" went from updates on my friends lives to 3/4 farmville useless announcements, making it effectively useless. I was tempted to install the app to see if I could filter them somehow, but ultimately said forget it.
It's fine if people want to play games, but frankly, the rest of the world doesn't care or need to know that you planted seeds. If I installed a facebook app that broadcasted every time I got a green drop in WoW I'm sure my friends wouldn't be too happy.
Add to this the Mafia wars spam, and these stupid little apps have made a mess out of what was once a useful tool for me to keep on top of my friends day to day and related silliness.
It takes one click to block an unwanted application like Farmville from posting to your News Feed. There's a "Hide" option on any News Feed story which will block all posts from that application. Very useful.
Without life, Biology itself would be impossible.
