Failure

Failure is a part of a free market. It's known as creative destruction. It's also the nasty part which no one wants to see happen, especially when it is your own invest which has been "creatively destroyed."
What would happen if we didn't allow this process to take place? I wouldn't be typing this on Blogspot or even a computer, the quality of everything would be down. Products and services sell when they provide higher quality than previous products or services.
In this way, when everyone has the ability to enter the market with a new idea, the good of the greater society is served. It is this right to enter the market which government must protect. The entrepreneur should also be able to have his property, both physical and intellectual, protected from the encroachment of others. These are the rights government should protect.
Everything gets messed up when we confuse those creative rights with the right to a job. For instance, many people lost their jobs when typewriter sales went down due to personal computer sales. Imagine now if those typewriter special interest groups had gotten government to protect their industy by heavily taxing PC companies. The jobs of thousands have been saved, their children can still go to school, ensuring a better life for potential more thousands, right?
Look at the benefits PCs have brought to the world, especially with the advent and proliferation of the internet. Imagine if the "rights" of typewriter manufacturers had been protected.
(This example didn't come from my own head, I read it somewhere and it stuck in my brain because it's a good one).
Also, I am not saying PCs are the embodiment of everything good on this earth. They've allowed also for the proliferation of evil ideas and bad ideas at a more rapid pace than the typewriter allowed. Still, the overall quality of life around the world has improved because the idea of the typewriter was creatively destroyed.
