100 Billion dollars?! Isn't this just tax payers money that could be used on health care keeping our broken aviation industry running? I wonder what a 100B train project would look like...
$100B spread over 5 years wouldn't make much of a dent in health care. We spend over $4T per year on health care.
I agree that the airline industry has significant problems to be solved but I'd hardly call it broken. Annual US spending on airfare is a little less than $350B. There are nearly no accidents. Approximately 45% of Americans fly commercially in a given year.
As to high speed rail, I would love to see it and I'm sure it can be done more efficiently than it has been in CA. That said, the California high speed rail project has, so far, cost about $128B. It has been in the works for 15 years. About 120 miles of the originally planned 500 miles of track have been laid.
So, I don't think that your criticism is valid. There may be valid criticisms of the legislation but saying that the airline industry is "broken" and this should be spent on health care (with no identified plan for how to spend it) or on high speed rail is a lazy argument that seems like it is being made for the sake of arguing.
