Lol. I'm not saying you're completely wrong or anything here dude... I agree with you for the most part like I said... All I'm saying is that you're trying to make it seem like America's growth back then was the greatest thing to ever happen to the face of the universe, when at the time, it wasn't all the tits that you're making it out to be.
No no, I was not comparing living conditions back then to now so much, I was saying that, for the poor, its not like they were making such a fucking awesome living as you seemed to make it out to be. Yeah, capitalism lowered prices, and made it so they could afford more things they wanted, they had more purchasing power, bladdy blah.. but It's not like they were living a whole holy shitload better... The poor and working were still living 14 to a  10x10' shitty slummy building that was falling apart and not built to any safety code, and sometimes seemed like it was going to fall out of its foundation when the wind picked up at times.. The biggest difference is they were just living in America... which was far better than the persecution and bullshit they were dealing with in Europe or wherever else they were coming from at the time... Remember... there was a crapload of people coming over here for other reasons than hearing that it was just some giant goldmine (although... I guess in the case of the millions of people who went out to California for gold, it at least sorta was).
Children were actually put to work a lot of the time in factories because they had small hands, and could un-jam machines, and stick their tiny hands and appendages in places that adults frankly, just couldn't reach into.
Carnegie and Rockefeller and Vanderbilt... Glad you brought them up, because I was going to. They didnt lower prices because they were on some mission to help people. They lowered their prices to fuck their competition in the asshole, and rightfully so. Rockefeller did it so well in fact, that he eventually killed off ALL Standard Oil's fuckin competition, and had a monopoly on the market.. Then Standard started charging a fuckload on it. (if you think gas going to 4.50$ a gallon 2 summers ago was a lot.. shit... it would have been like it went to 17$ a gallon back then when the prices were raised from where they were) While, this is way less than what it was when the industry started growing, it was still obvious what the intentions were in charging exorbitant prices...
It got so bad, that there was downright public outcry from everyone to the extent that the government HAD to get involved and lay down the law. If the government is so fucking evil, and shit as you seem to be making them out to be, and Capitalism as it is, is so fucking awesome as you say, then who in capitalism was there who could have stopped Standard oil from just raising the prices on oil right back to where they were? that whole 90% drop in keresene, as well as anything else could have gone right fuckin back up if there was no significant competitor - which there was not.
As for Amtrak.. I only compared it to flying because YOU did. Duh. lol.
I dont know... All I can say is, yeah... capitalism has it's place, obviously it's done great and made most of our innovation possible, but are you saying that we should unregulate shit, abolish the government, and just let all this shit run lassaiz-faire all the way through? I dont know dude... I see how that worked when America was 30-40 years ahead of every other country in the goddamn world, who were being run by greedy kings and just wanted to test their soldiers on the battlefield against their rival or something... but today? fuck that shit. The world's caught up, and they caught up in countries that tax the richest 1-2% way more than we do...
as for the road... how about comparing it to space? Before the soviets sent a man into space (uh.. centrally planned haha) before anyone else... people had been looking up since they had fucking eyeballs, thinking they wanted to go up there... There are stories of chinese guys during the Ming Dynasty, strapping a shitload of fireworks to a chair, aiming it straight up, lighting them all up and exploding into a raging fireball of LOL... The french tried to do it with balloons during the 1800's and realized that space was a lot fucking farther than they had previously thought... then they realized air just gets way fuckin thinner the higher you go up and its kinda impossible. Astronomers for years looked through telescopes that had homemade, hand carved lenses, just to see what the fuck was up there... Hell.. Leo Da Vinci even came up with a goddamn rocket ship idea he was working on for taking off and going on a vacation on the moon... but unfortunately, humans die, and he couldnt live long enough to complete it, along with his bagillion other inventions... So... going to space wasn't exactly a NEW concept when Yuri Gagarin was kickin it in outer space for the first time...
With that said, by your logic, going to space is 60000 years un-innovative... 200,000 years un-innovative if you want to get real primitive with me... That puts a giant damper on "one giant leap for mankind" now doesn't it...
The point I'm making here is that, just because people had thought about it doesn't mean they had the means of  actually doing it...
It took some people in Rome to say, "you guys, in the sweet helmets and skirts over there, get 20000 italians to stop playing soccer and go gather up a fuckton of cobblestones, and lay them flat in a road, 20 armlengths wide, between Rome and Milan so we can roll our bling'd out chariots from here to there a lot faster in case some asshat germanic tribe flips out and attacks, because WE MUST PROTECT THIS HOUSEEEEE''
