European here. Why would someone intentionally design a useless bus system?

This is compounded by the fact that in most of these types of cities, most of the jobs and/or the "best" jobs (highest paying, most stable, best health insurance benefits, etc) are located in the suburbs, where transit is least available. Often these places can "opt-out" of transit altogether.

The "X cost system" is worse than the "2X system". That's why it's cheaper.
The "X" system is slower or carries less passengers or runs less often or goes to less places, or gets stuck in traffic, or is less reliable, or changes it's routes.

It's like comparing a WalMart Netbook to a MacBook Pro and saying "they're both 'identical' computers, why are we spending 2X on the MacBook Pro?".
We spend the extra cash because they aren't identical, the 2X one is better.
With your notebook computer analogy, the extra cost of a MacBook Pro is not a benefit. The benefits are all the various things that are better about it, with the extra cost being worth it to have those benefits. The only way you'd say the extra cost of a MacBook Pro was itself a benefit would be if you wanted to show off how rich you are or something equally silly.
For many people, Light Rail (or trains / subways) are the only decent mass transit they have ever experienced in the US.
Every single major and minor city has a bus system. Most of them are nearly useless, often intentionally so by design. It's natural for people to demand something useful, and light rail is nearly universally more useful than busing (including BRT) in any given market.
> It isn't flexible and its cost per mile is staggering let alone the cost of maintenance.
Those are benefits of light rail, not drawbacks. The higher costs and inflexibility of light rail represents an authentic long-term commitment to good useful transit in that area.
To replicate that value with a Bus system requires you to build grade separated, dedicated right of way. Which is where 90% of Light Rail's cost comes from. So if your going to spend that money, you might as well put in real Light Rail and get all of the benefit.
