@oralloy,
Well, that's the same here, since 1872.
But nobody would make the wins of Deutsche Post from their parcel and letter service responsible for the DHL-groups payments for the payments to the mandatory health insurances and pension fonds. (The the US Postal Service has enjoyed double-digit increases in revenue from delivering packages, but that hasn't been enough to offset pension and health care costs I've learnt by now. And I've read, that similar to the situation here, as well as the Post Office, Amazon uses FedEx, UPS and other services.)
