It's a good quote, but it's not a replacement for "power corrupts" because a shift from calling an action immoral to not calling that action immoral doesn't in itself equal corruption. "Power" / "being able to afford something" can be concomitant with "is now commonly available" / "newly invented technology", and such a gradual shift of society to accept the new status quo wouldn't typically be perceived as corruption.

Example: Someone who thinks of new anti-aging technologies (whose price points are gradually dropping) as immoral, then -- upon being able to afford them -- thinks of them as immoral no longer hasn't necessarily been corrupted, but may have simply been incentivized to dwell upon the matter more thoroughly.
