By "more" do you mean "better"?
As others have said, not always. And even when it does the amount of money spent may not be in proportion to the increase in quality.
Better to spend a little time either researching the product or shopping around.
Sometimes yes, often no.
Ask @ohphukimintrouble if all those apple products are worth the pricetag.

My experience on this is a definite "yes".
Sometimes, but definitely not always. Spending more can often just be because something has a brand name or is a luxury. Some people think they need to spend $400 on a Yeti cooler when tests show that a $55 Coleman Extreme is just as good if not slightly better at being a cooler. My friend and I each had the same pair of Oakley sunglasses a while back and both of ours fell apart and the frame separated at the hinge. My $10 polarized sunglasses don't fall apart and work just fine. While Maserati cars are really nice and really expensive, there was always a saying "if you can afford a Maserati, then buy 2 because one will always be in the shop."
With my limited experience of being able to afford spending whatever I want, that hasn't rung true for me. I still buy most of my nail polish and hair products at the supermarket. The expensive brands have flashier packaging, but aren't any better.
Fancy cars are a guy thing, but my Accord hasn't needed anything but fluid changes and new wipers. Peter's fancy continental's been in the shop >5 times in the last two years.
There are some things worth insane spending - KitchenAid/Hobart mixers, Viking appliances, etc. But you still have to be very diligent when comparing products and not let a high price blindly sway you towards that item thinking that it's price makes it better.
