Broomless flight is a technique like apparition and not a spell. In order to disapparate, you need the 3 D's (Destination, determination, and deliberation), after that, you just turn on the spot and disapparate. I think flight is similar, without any spells involved, just your concentration, willpower, and magic. Perhaps in order to teach Snape how to fly, Voldemort had to drop him off a mountain as some birds do. - Wizards are superior to muggles in many ways: All of them are magically resistant to blunt damage and mundane attacks. Their intelligence, memory, reading speeds, and other things can also be superior, it does not apply to all wizards but some like Hermione are supernaturally intelligent, she can read several books over the course of one week (This is canon) and her memory is extraordinary. - Their reflexes and reaction time are also superior, with Quidditch players being proof of that. Imagine racing on a bike with 6 other people while trying to pass on a ball, meanwhile, there are two 60kg balls of iron flying around trying to knock you out. Not sure how good this example is, but a normal human could never play quidditch. - Capturing the snitch is only worth 70 points, it's as if each member of your team had scored 10 points. - A Galleon is worth One thousand pounds. Muggle money is practically worthless and goblins only accept limited quantities of it. Wizarding minimum wage is 4 Galleons a month. A galleon is exchanged much less often than a sickle or a knut. Wizarding goods are priced according to offer and demand. So if you can mass-produce an item and there is not much demand for it you sell it at a low price. If it's a highly desired object like a Nimbus then you control the offer by selling it at a higher price. A brand new Nimbus costs 20 galleons, a Firebolt costs 150 galleons. Omnioculars only cost 1 sickle each. (Could sell for 2 at Sporting events). Chocolate frogs only cost 5 knuts each. They cost more than pure chocolate because of the cards. Brand new Spellbooks cost at least 2 galleons if they're still being printed. New plain black robes cost 1 sickle each. The Weasleys are poor due to bad financial management, like many families they try to pay for everything with their monthly salary alone. They rarely ever save any money. There are wizarding taxes but they are lower than their muggle counterpart. The cheapest wand at Ollivander's will cost you 30 galleons. Most parents just buy their children a cheaper wand from some other wandmaker just so they can go to school. Cheap wands cost 5 galleons at the minimum. Food is generally cheap. Food and drink at pubs are more expensive, you pay for the experience. A bottle of Butterbear at a pub will cost you 4 knuts. The salary of an Auror starts at 20 galleons. Healers earn the same. Nearly all Non-magical goods are cheap and will cost less than a sickle per item. Robes included. Magical items are priced according to offer and demand, of course. Pure gold, silver, and precious gems are also priced according to offer and demand by wizards (They don't necessarily match their muggle counterpart). Figuring out a perfect exchange rate between muggles and wizards is impossible because you would have to consider how much a muggle would want to pay for wizarding goods. Any muggle billionaire would easily pay dozens of millions for a real broomstick that can fly, even if it's an old one. That's why muggle money is practically worthless to wizards, they only care about their own internal currency.
