Republicans are making state workers pay into their pensions here in the US ( see rRepublican & Tea Party governor Rick Scott in Florida's recent budget) Most of us involved in a 401k have to pay in. So, yes, I'm in favor of changing the way government pension plans work today.
That has nothing to do with the federal budget.
But you want to change Todays federal pension recipients? I think that goes back to the OP's original post of people like their entitlements and your politicians like their comfy job so it's easy to get votes by promising current recipients that you won't reduce their income. You'll give algore a reason to hit the newsshows with his 'lockbox' BS.
