This, and the post about middle-class flute-playing being indistinguishable from working-class flute-playing are some of the most hilariously tone-deaf things I've come across on here, which is saying something. Let me spell this out, because it is clearly necessary to do so. The vast majority of
Beavers, Scouts, Sea Cadets, Piano, Guitar, Glider Lessons (not as expensive as you'd think), brass band, gymnastics/trampolining, tennis, skiing, body boarding, wakeboarding
are absolutely beyond the reach of many WC families, regardless of the virtue-signalling about driving a 21 year old car.
I come from a poor WC family, and I was actually enrolled at primary school (by teachers, who chose me not because of any musical ability, but because they thought I could best cope with time out of lessons without falling behind) for a 'Deprived Children Music Scheme (I kid you not this was written on the form my parents had to sign) and was allocated the cello. I was lent a half-size cello for the first six months, fair enough. But the scheme, while well-meaning, had no idea what it was asking. A parent had to sit in on lessons, and my mother would have had to bring all my younger siblings with her, and we had no car or money for the bus, so I was lugging a heavy instrument the mile back and forth to school with me for lessons twice a week. And I had literally nowhere to practice we had a kitchen barely big enough for a table and chairs, a living room which was a corridor space between the bedrooms and the kitchen and loo, and the bedrooms were all so small there was barely enough floor space to stand up in. I had to practice when both my sisters were out of our shared bedroom, and I had to so it sitting on the bed with the cello in the two feet between the bunk bed and the single bed.
I persevered, but then we couldn't afford to buy even the cheapest second-hand cello, so gave up then.
TL;DR . It's hard for poor families to give their children what you blithely term 'life experiences'.
