> More importantly, try arguing that it is morally correct that a hard-working laborer ought to fund a Webb telescope by non-optional taxes, when he sees no direct value in it. Why even 1 penny? Because his betters in a grant agency know better what to do with the fruits of his labor than he does?

There is an optimal level of spending on basic research for society, and it's not 0. Was it a bad idea to launch unproven satellites into space in the 1970s? Your laborer didn't see the immediate benefit, but now that worker has GPS, which almost certainly improved the worker's life. In fact, the technologies enabled by GPS were unimaginable at the onset of the project. Should the project have been scrapped entirely?

It's impossible to say whether research will produce valuable results a priori. But it's not true that your laborer doesn't see benefit. The price we pay to live in organized society is taxation. Should that same laborer argue that he shouldn't pay taxes for highways built 400 miles away? Is it possible that this laborer may not know what's best 100% of the time?
