Nope. Not the Tom Selleck series.
It's strange how notions get planted in people's heads.
Blue blood is a classic.
English idiom for nobility from sangre azul because the Spanish royal family etc claimed to be of Visigothic descent, contrasting the Moors. Go figure.
It distinguishes an upper class whose veins showed blue through their pale skin.
This is contrasted with the working class, agricultural peasants who got very tanned working in the sun all day.
It's probable, and I know my St. Clair ancestors were among them, using silver utensils and some people apparently got a bluish cast to the skin (argyria), though I don't think the St. Clairs did. But they bathed, were literate including the women and beat devastating loss during the Black Plague.
Veins appear blue because the subcutaneous fat absorbs low frequency light, permitting only the highly energetic blue wavelengths to penetrate through to the dark vein and reflect off.
It's the impressions and labels people apply that really interest me.
Most of this relies on people not thinking, just accepting.
Sounds familiar huh?
Suffice it to say it was promalgated that nobles and commoners are different.
Except that conditioning makes people certain ways.
If we accept that we are different, then it appears so.
If we have a Constitutional Republic, we see those differences shift.
We of course, have rich and poor and middle class.
But, we all should have a chance to improve our lives as we see fit.
Government has interferred with this such as the war on poverty, to create a divide of haves and have nots to pave the way for a collectivist 'paradise'.
The secret is to teach that we are free. Free in the heart is the start of giving each person a chance to do and be better by teaching self reliance.
No blue bloods.
Only red human blood, which has and will be shed again for Freedom.
