It really does. The classic example I think of is Michael Caine discussing when he wanted to do housing renovations, and before he even submitted designs, he had neighbours and councillors complaining it was going to be "vulgar," "nouveau," and "obscene" simply because of his class. He also talked about the concept of working class people furthering the divide, for example his female family members referring to women of the correct class as "proper ladies" and putting themselves down.
I go back to the UK every so often for work. Being in EU countries is really weird, because they don't have 'class systems' (like the brits).
Deference is given to your professional title, doctor, lawyer etc.
Every nation that was a heart of an empire still has lingering class issues. I've been told by Swedes a non-commoner last name can absolutely open some doors. Though nothing comes close to the UK, which is closer to Japan in this regard than the continental Europe.

What nation on Earth doesn't have class issues?
Belgium has a class system. Read up on the death of Sanda Dia, very light punishments since all suspects had well connected parents. Lawyers, judges, doctors, surgeons, business executives, entrepreneurs, bankers, corporate directors, politicians, senior civil servants, police officials.
