You should include what country you are talking about. I know nobody in the USA who had an arranged marriage in the 1950s. They met partners at school, church, and neighborhood/extended family picnics and parties for the most part. They met in stores, libraries, and cafes. We have to maintain public casual community spaces. To paraprhase a Sociology professor I once had: you can’t marry someone you never meet. It requires talking to other humans to make even casual friends.
