Yeah, that "'80s materialism" thing has come up before, and there's plenty of movies where it's true, but I think it's been played up too much here. They live in the same house in the same neighborhood. The tennis rackets just means they play tennis together and are still active. Shit, the truck is a Toyota not a Porsche or something.

Yeah.

I mean, has Glover even seen the beginning of the film in the last 30 years? Marty's home and family at the start of the film appear to be just barely over the poverty line. It's hardly "80s materialism" to want to have a sound roof over your head and enough money to put food on the table.
