A person needs to look at Mari P as a vehicle just like your car.
Lets say you have a 78 Pinto Station Wagon and it still runs.
This Pinto gets you to your $150,000+ job every day. What is this Pinto worth? Well it is worth $150,000+ to you b/c it gives you to the opportunity to make $150,000+
Now Mari P they say is worth $22,000. But in fact it is priceless b/c of the opportunity it provides its many members to endure life in a happier/pain free environment. What price does one put on a vehicle that provides a happy and wonderful life?
Now if one was to say "kick the tires" they may feel that this is a lemon, and want to lower the price, but in reality it is a rose for all the opportunity it affords us all
