I don't know if it is "as useful as spending it on science education"....but to the general contractor, sub-contractors and other tradesmen working the project it's very useful. In many cases these contractors live in or near where they're working and they in turn spend money they received back into the local economy. It might have suppose to be a bridge to somewhere but the contractors and subs have no control over those budgetary matters...yet they still need to get paid for the work they've done....which for the most part has the cyclical effect of going right back to other businesses for goods and services.
To build a bridge to nowhere is of no economic value. People no doubt liked being paid for labor & materials, but if the end result isn't useful, then it's wasted. Only wealth was transferred. Compare this with building a bridge which reduced commuting time for people, & saved perhaps 1 million man hours each year. This is something of real value, & not just mere make-work money transfer from taxpayers to favored contractors.
I can see what you mean here...but then again if they are government property the government can turn around and sell the artwork. (See:
Detroit Art Collection Bankruptcy Plan on Drawing Board - WSJ.com)...
To 'invest' in collectibles is a dubious use of taxpayer money.
I begin to see why the lefties love big gov spending, & favor tax increases. In their eyes, there is no such thing as waste.
It's the spending itself which matters, rather than getting value for it.
But consider this: There are always limits to gov budgets. Are vanity paintings the best use of the money?
Could things like health care or food for poor kids be a better use, while still plowing the money back into the economy?
