(EBMSP) Patrimonialismo é um modelo de administração, típico dos estados absolutistas europeus, e tinha como principal característica a não distinção entre o que era bem público e o que era bem privado. Em outras palavras, não havia distinção entre o que pertencia ao Estado e o que pertencia ao detentor do poder, no caso de Portugal, o rei Dom Manuel I. Se esse modelo estivesse vigorando, hoje, no Brasil, seria o mesmo que dizer que o presidente da república seria dono de todos os bens do Estado brasileiro: móveis, imóveis, utensílios, acessórios, enfim, tudo seria dele porque, no Estado Patrimonialista, prevalece a seguinte mentalidade: tudo o que pertence ao Estado pertence, também, ao detentor do poder.

Read the following text from CNN. (CNN) -- There's nothing like getting stuck into a good book -- but getting stuck in a good book store is a different matter. Just ask David Willis, a tourist from Texas who was inadvertently locked inside a London retailer for several hours, after strolling in minutes before the store was closing. Willis, from Dallas, entered the Waterstones store near London's Trafalgar Square on Thursday evening to use the store's Wi-Fi. "I walked into the store about five minutes before 9 p.m.," he told the UK's ITV television network. "I walked in right past employees and I needed to use the internet... I peeked up on the second floor and saw there were chairs and a table up there so I walked up there and was using the internet for 10 or 15 minutes and all the lights were on upstairs. "I get ready to leave and I walk down and it's completely dark and the doors were locked." Willis said despite setting an alarm off by trying to open the doors and speaking to a security guard and police via telephone, no one came to his aid.

(UERJ) Little Red Riding Hood
There once was a young person named Little Red Riding Hood who lived on the edge of a large forest full of endangered fauna and rare plants. One day her mother asked her to take a basket of organically grown fruit and mineral water to her grandmother’s house.
– But mother, won’t this be stealing work from the people who have struggled for years to earn the right to carry all packages between various people in the woods?
Red Riding Hood’s mother assured her that she had called the union secretary and had been given 1a special compassionate mission exemption form.
2– But mother, aren’t you oppressing me by ordering me to do this? Red Riding Hood’s mother pointed out that it was impossible for women to oppress each other, since all women were equally oppressed until all women were free.
On her way to grandma’s house, Red Riding Hood passed a woodchopper and wandered off the path in order to examine some flowers. She was startled to find herself standing before a wolf, who asked her what was in her basket.
– I am taking my grandmother some healthy snacks in a gesture of solidarity. Now, if you’ll excuse me, I would prefer to be on my way.
Red Riding Hood returned to the main path and proceeded towards her grandmother’s house. But the wolf knew of a quicker route to grandma’s house. He burst into the house and ate grandma, a course of action affirmative of his nature as a predator. He put on grandma’s nightclothes and awaited.
Red Riding Hood entered the cottage and said:
– Goodness! grandma, what big eyes you have!
– You forget that I am optically challenged.
– And grandma, what an enormous nose you have!
– Naturally, I could have had it surgically fixed, but I didn’t give in to such societal pressures, my child.
– And grandma, what very big, sharp teeth you have!
The wolf could not take any more of this, grabbed Little Red Riding Hood and opened his jaws so wide that she could see her poor grandmother in his belly.
At the same time, the woodchopper burst into the cottage, brandishing an axe.
– Hands off!, cried the woodchopper.
– And what do you think you’re doing?, cried Little Red Riding Hood. If I let you help me now, I would be expressing a lack of confidence in my own abilities.
– Get your hands off that endangered species! This is a police raid!, screamed the woodchopper.
– Thank goodness you got here in time, said the Wolf. I thought I was a goner.
– But mother, aren’t you oppressing me by ordering me to do this? (ref. 2)
