I live in a very poor, working class area. Grew up WC. Just scrape into the LMC now.
My observation is that MC families seem to be oriented outwards, towards the wider world.
So things like trips away, travelling to and from extra curricular activities, educational visits to places. Relatives and friends living in other towns or possibly other countries.
WC families seem to be oriented inwards towards the home and the immediate neighbourhood.
Partly because there's less money to go places.
But also because they may experience the neighbourhood more richly. Family and friends may live near by. Neighbours may be well known since childhood. Kids play out.
By contrast, MC people seem to use their immediate neighbourhood almost like a dormitory or a base to set out from. Which always seems a little sad to me.
I agree with the PP who said WC families are more likely to spend on experiences than things. And I think this is to do with a sense of place. The "things" are to enhance the home environment and make being at home more fun.
So yes to toys, TV/Streaming package, consoles.
But also bikes/roller skates/scooters for playing out.
Also pets. Which tie you to home by requiring someone to care for them. But can make being home more fun and rewarding.
