How do we get "wealth" in whatever currency, in more people's hands, without just giving it away. How can a better technology like Bitcoin achieve that goal?
In simple terms, it can't
Bitcoin doesn't itself produce any wealth on its own. At the best of times, it is only a currency (or a store of value) and its purpose is purely utilitarian, i.e. being useful for something else. Technically, you can use it as a service (for example, by taking fees from processing Bitcoin transactions as a miner or a payment channel operator) but it is no different than any other service out there and requires basically the same things (e.g. initial capital, resources, dedication, etc). To sum it up, it is not a free launch
