Great post... btw much luck is earned... nice work.
Let me share a thought about what you describe... I grew up in a neighborhood like that... they were very common in the US in the 50's, 60's, 70's, and 80's... I would say in the 90's I noticed the tectonic plates shifting.
I worked for a large corporation in the 90's... and I'll never forget the first mandatory "multicultural" training I had to attend. It was DEI before DEI came onto the scene.
Long story short, imo life was simpler, satisfying, and more enjoyable back then. And I know many people that would love to travel back in time and live in a neighborhood like yours.
Embrace and cherish what you have! And may we work to create and .maintain an environment like that for our kids and grandkids.
