If you're a Rails dev, yeah you're valuable and you should be getting paid that much.
However, you still have a lot to learn, and if you're asking for telecommuting and you don't even know what a thread is. That's entitlement, because you think that just because you know Rails, anyone will hire you and that you're 'good enough' to work from home.
Developers we'd want to hire don't just know Rails.
They are asking for them out of increased awareness of their market value.
In the end the market will sort this out, and some developers will inevitably be left disapointed.
However, I think it's quite reasonable that techies of all skill levels are pushing for and often achieving the salaries and working conditions that they want.
(I really don't see how asking for telecommuting is entitled by the way. I would love to do it for quality of life and productivity reasons, but that is completely divorced from how well I rate myself etc.)
Do you think you deserve a better quality of life than say, a teacher? a doctor? I fail to see how even comparing yourself to them is not entitlement, especially if you're not a CS major.
The whole productivity bit is crap, I've been on that side and I know it. You may be more productive, but for very selfish reasons. The business is not more productive, and you isolate yourself from everyone else.
Businesses don't generally fail because of bad tech, they fail because they're not nimble enough to adapt and test ideas quickly.
