You're getting older, I can feel the bitterness starting to flow from you.
Truthfully, it's not up to us to determine what is too much or what another person needs or doesn't need. It's their money, why worry about it at all? If they have it, then they should enjoy it as how they seem fit to spend it. I know that this site is filled with jealous peasants. I honestly couldn't be effected by another's spending habits on their guns.
As for glass, the cheapest red dot that I would trust is an Sparc AR. But it's not an H1 or a T1 in quality. I'm a fan of good glass and if you ever plan on shooting further than 100, even 200 yards, then the adage that one buys what they get applies. You want hits at 800? Then most of the time a sub 500 dollar optic is not the answer.
So with the above said, only accurate rifles are interesting. That means you have to pay to play and good barrels are not cheap, neither is the glass or sometimes the trigger. The rest, is all subjective. Lightweight isn't cheap either. Sure cheap parts will work but at the heft that adds up, I'm more than willing to spend the money to bring the numbers down.
I think that it may be best to just do you and not trying to keep up with the jones. Your heart will thank you for keeping the blood pressure down.
