Now let's put things in another perspective and take into account non-US webmasters, EU-based to be more specific. You may do quite well on that $3-4K/mo in say Poland or Czech, but if you'd compare with Germany then you'd probably be better off working in a factory, making about the same or more. Also, keep in mind that most EU taxes are a lot higher than US taxes, both income tax and sales tax. Also consider the fact that, as self-employed, you'll also need to pay some additional "social" taxes, which would normally be paid by your employer. So you may well end up paying about half that in taxes, as well as having to deal with higher purchase prices on just about everything, due to the 15-25% sales tax (depending on country). Factor in the weak dollar and you'd pretty much be better off having a day job.

So at the end of the day that money may not be all that much, as it is highly relevant where you live.
