You and 'you'

Unknown to speakers of some languages like modern
English is the formal or polite manner of addressing
another person common around the world. Languages
such as German, Russian, Spanish, French, Italian,
Portugese and many others use two forms of 'you'.

In English, for example, 'you' is how one refers to
another person, any other person and is singular as
well as plural. Anyone you meet or talk to is 'you'
no matter which socio/economic or familial strata
they come from. In other languages 'you' has a
Formal Form and an informal one and also a singular
form and a plural form. There are the Sie, usted,
vous polite forms in German, Spanish, French and the
du, tu, tu, familiar forms.

With friends and family, the familiar form is fine but
to use the familiar form of 'you' with anyone else would
be not only egregiously incorrect, it would be an insult.
One would never address a stranger with a familiar 'you'
or any one, in fact, who is not a relative or close friend.

For today's English speakers having such demands seems
odd, confusing and even stilted. Of course, many aren't
aware that 'you' used to be the polite form and 'thee',
'thou' and 'thy', phased out long ago, were actually the
familiar form of the second person singular, never the
formal.

Egalitarian movements pushed aside traditions and cultural
mores and perhaps 'you' separations in language forms as
well. Maybe 'you' became the commonly used form because
of ease and convenience, sort of a one size fits all.

Languages are always changing and in times of exanded
international interaction and communication, languages
are impacted on a regular basis. For the same reasons
that 'thee' and 'thou' disappeared, the two forms of
'you' are being converted into one in Brazil and in
some Spanish speaking countries.

Older generatons possibly would not accept a change
utilizing only one form of 'you', but younger
generations, connected to the world through the
internet, cinema, television and telephony, might
have no problem with it at all. While stepping away
from tradition and accepted structure, it certainly
seems logical to have one pronoun that in the same
friendly form applies to everyone.
Do 'you' agree?
