Charities: Where does the money go?

It has been reported this week that there are CEOs of national charities here in the UK with six-figure salaries.  The largest that I have seen quoted is £240,000 (about US$368,162 at the time of writing).  How reasonable is it for the CEO of a charity to take a six-figure salary?  Charities are, by definition, non-profit making organisations.  The money raised by the charity goes to supporting the activity of the charity, whatever that may be.  There are going to be administration costs and some of those are going to be wages and salaries, but surely having such a high salary is an expense too far?  Should the CEO of a charity really command a six-figure salary?  Or should a more modest salary be standard?  Is it reasonable to say that they should have a salary commensurate with a CEO in industry?  Surely if they want that kind of salary they should work in industry.  And if they have moved from industry to be the CEO of a charity, they should have stayed where they were because charity work, even the CEO of a charity, should not, in my opinion, come with a six-figure salary.  How these charities run themselves is, of course, up to them.  But does it really encourage people to give to charity when they know that the CEO is in receipt of a six-figure salary?  Or are they more likely to pull their charitable giving and use their money in other ways?  I would not be surprised if charitable giving goes down as a result of this, even to charities that are not paying the person at the top a massive salary and that will be a shame.
