Baseball is a hardware-intensive sport. It's hard to get popular in poorer countries. Soccer on the other side demands just a vacant lot and some soft round object you can kick around to get started.
Basketball is growing in Brazil a lot and that’s kind of expensive.
Skateboarding has become massive in Brazil and that’s even more expensive than soccer and every person needs their own skateboard, unlike soccer where you can pool your money to share 1 ball.
Idk what you are talking about, you don’t need fancy equipment to play most sports with your friends. Most of the time, it’s having the idea is the issue.
The limiting factor is historical: Brazilians just don’t think of playing baseball already.
Which leads back to the point: Americans just don’t really think about playing soccer.
It’s not about cost, or about leagues, or any technical thing. There’s nothing stopping me, as an American, from trying cricket with my friends, except that the thought has never ever entered my mind.
