One addendum
The federal agency claims (correctly) that it receives no funds from general tax revenues, but this is highly misleading. Where do the funds come from? The federal government charges companies who maintain pension plans, who pay the government by...taking the money out of their pension assets. So anyone who's working or retired with a pension plan is affected.
And of course when the federal agency gets in trouble and needs a bailout it will go straight to Congress with a request for funds which will come out of...general tax revenues.
