Agreed. Even if it's more commonly allowed, I suspect that there is a measurable reduction in productivity for "work from home." That would tend to offset the COL differential, so that salaries wouldn't equalize completely across the country. It still may pull salaries down in the high COL areas though, due to increased competition from the labor expanded market. One possible interesting side-effect: it may result in 'democratizing' tech to some extent, if enough seed populations of engineers remain in the lower-COL areas and continue to work remotely.
