I agree, egslim. But I don't agree without limit, and I also think that the investment should have at least some possibility of return. High-energy physics, as practiced today (though not so in the past) really doesn't express that possibility. I think it is too large an investment for the science we get from it. I think the money could be better spent on more, less expensive experiments.
I'm more than willing to be convinced others because, as I said, I like high-energy physics. The results are interesting, just not useful.
