Many thousands of programmers spend hours each week in pissing matches online. Why is it none of them feel like truly putting their money where their mouth is?
Writing a "Hello, world" is going to take about the same amount of time in any language that isn't a turing tarpit. At issue is generally some sort of asymptotic advantage, not a guarantee of "language X will always be superior every time always". In fact, for any pair of one easy and one hard problem, I'm pretty confident I could find (or invent, if necessary) two languages that each beat the other for solving one of the problems.
The claimed benefits of a more expressive language generally involve things like better management of application complexity, or greater ability to modify and restructure late in the project. Hammering out a program of a scale such that the programmer can keep an accurate model of the entire thing in mind at one time, and that is only written and never modified, would be more a measure of the programmer's typing speed and the sophistication of the IDE used than anything else.
