We all pay taxes that build and maintain our roads, but that's no reason to not shell out for an airline ticket if we want to get somewhere faster.

In my country I can see a doctor for free after a 0-4hr queue in a hospital waiting room or pay USD$10 to immediately see any of the dozen private doctors within a 5 min drive of my home.

My taxes already pay for free healthcare, but I'm more than happy to pay more to avoid wait times.

But I live in the "third world", so I understand your experience might be different.
