Competition brings out the least in people.
If you measure yourself against the world, you'll always have room to improve.
If you measure yourself against other men, if you're the best, you'll never reach your potential.
And, because your peers have motivation to celebrate your failures, rather than your successes, you'll actually be fighting those who should be benefiting from your achievements.
On a personal level... dealing with competitive people is too tiresome to bear. Nothing they have to offer is worth dealing with their ego driven crap.
And, you can see the idiocy in their posts here. ISPs in the states are the most "free market" in the world, and they are also among the worst. The countries that treat ISPs as critical infrastructure like roads are the ones with the fastest infrastructure, but the "free market ra ra ra" crowd are still convinced that the way to improve the situation is to move further away from what is working better elsewhere.
Now, this isn't an academic debate. When you can look around, see that other people are getting better results, and you ignore that, that is just plain stupid.
