its silly on plenty of levels. for instance, it makes sense that china's trains are being upgraded more than ours because of the amount of people they must accommodate.
the roads, vehicles, and traffic in the US make driving much more desirable than in china. focusing on railroads is probably more of a necessity than it is here in the US.
its silly because whether or not we are funding wars has nothing to do with how much money is going toward our trains.
its silly because the they compared an old freight train to what seems to be a very modern passenger train. which is like comparing a 1980's 18 wheeler to a 2005 state of the art RV.
its silly because china can have nice and neat trains but how free are they to go on the internet and bash their own country?? or even make a slightly provocative political statement without it being censored?? freedom of information > trains
its (your statement) silly because if china literally owned the US then that would mean the same thing can be said about the US literally owning china. assuming you're talking about 1 of 2 things. 1 being the debt that we're never gonna pay and they're never gonna do shit about. or 2, how many products come from china, people always like to insinuate that china has any power over us because of this fact without taking into consideration that our economies are dependent on each other because if we didnt buy from them they would collapse faster than we would if they stopped selling to us...its mutual.
I could keep going, but that would just continue to take away from this clever photo
they may have nice trains, but we still whipped their ass in the Olympics, even on their home turf.
