So is the US government! They poured $1,4 trillion into Iraq and Afghanistan.
Those expenditures are still around: they built the roads, runways and skyscrapers that we all use today.
Why do developing countries spend a lot more on development than developed countries do? That's almost a tautology.
Biggest waste of public funds in a generation. And mostly used to build further infrastructure such as roads, burdening the maintenance budget even more. Instead of helping.
A certain little jaunt through the middle east would like to have a word with you.
I don't think it's as simple as "we're developed now". Is there some arbitrary set point at which a country is completely "developed" and we should just stop doing things? Why is there such an aversion in this society to "spending money" as if it's something that we are losing rather than simply putting people to work and generating economic output. The complete gridlock which has gripped the US over the past 40 years has left vast amounts of the population sick and dying with no hope for anything.
Do you want a limitless money sinkhole with largest positive externalities and quality of life effects? Try science.
.... Kind of, and much of what we have could be upgraded. Some folks can't get clean water out of their taps (lead!), some folks have really crappy internet (dial-up or otherwise slow speeds). I'm pretty sure some areas could use an electrical grid upgrade. Railroad tracks laid long ago now block traffic and some crossings have a lot of accidents, and could be rerouted (some communities have done so, such as lafayette, Indiana). Many of our bridges are in disrepair.
On the whole though there are a lot of perfectly good roads and houses that just need a little work to keep them up. It is better to not build more than we need. I could tear down my perfectly good 2000 sq ft house and build a 4000 square ft house - but my current house is big enough for my needs so I'd rather sit back and relax.
St. Petersburg shut down a sewage treatment plant last year, and in the same year spilled 200 million gallons of sewage into the bay. For that, the city faced an $820,000 fine, which seems incredibly light. Just Wednesday this week, the city spilled 50,000 gallons of 'mostly treated' sewage into the bay. I can't image that St. Petersburg is the only city with this type of problem; though, I hope I'm wrong.
we have been at "war" for 15 years
This makes a lot of sense. I constantly get the feeling in the US that we don't actually "do" anything anymore. And I don't just mean manufacturing. You look around at the rest of the world and infrastructure programs are at the forefront of every expanding economy. China, India, Turkey. All pouring hundreds of billions into great works at home and abroad.
Where are the massive capital expenditures we saw in the 19th and 20th centuries? America has the largest population of highly skilled, financially endowed consumers on earth yet the most that any genius Venture Capitalist can figure out to do with these billions in free money from the fed is come up with a new skin for IRC.
