It's more "I need a new X" and because for years you've seen adverts for "X supplied by Y" you think "hmmm I've heard Y make good X I'll get theirs over Z's"
So what you are saying is that adverts have a monopoloy over information and what is known?
Luckily we now have the internet. Anyone who can use google can find the:
cheapest, most high tec, biggest screen, etc TV or other electronic device they want.
So Z wins.
Also with reference to the rather facile argument over Equality.
Equality does not mean Same or Identical.
It means we should all be treated as we would like to be treated. that all should be treated equal irrespective of race, religion, creed, hair colour.
One way to do that is the veil of ignorance. Imagine we all have a say in the creation of a new society. We all die and are brought to life in X position/background and genetic disposition in that society.
But if we dont know what our situation will be in that society then it makes logical sense to ensure that all have the opportunity to attain that which their will can make so.
Its about will. Some are content with only doing so much and some have different ambitions.
As long as everyone gets a fair crack at it. Its all good.
disclaimer: obviously this extends only so far as is practical or medically possible e.g. im not suggesting for a second that someone with downs syndrome that its possible to ensure that they have an equal crack at everything that someone without downs syndrome would.
