what I want to know is why planes aren't filled from the back; if the richies want to get seated first and watch us po pos so be it, but why have everyone be in everyone elses way?

I've been on planes that have 2 ramps and load/unload from both the front and the back. The boarding order is by seat row. It's pretty rare though.
To answer your question though - they paid a lot more for 1st or business-class ticket, and so their "priority" is they get to get on first and off first, rather than stand around in line. But every plane I've been on, they will board handicapped people, and families with small children first, even before 1st class passengers.

This is the 2nd video where the author got the Concorde story wrong... It became profitable 8 years into service (1984), largely due to BA raising ticket prices and making it more of a luxury. And the Concorde division remained profitable until the crash in France, when they grounded all Concordes while they investigated the root cause. After they started flying again, people were still wary to buy Concorde tickets, and airlines could get more profit out of 1st class tickets on larger, slower planes. So both BA and AF phased them out ~2003.
