If you live in an area that has good public transport, than why drive your own car for regular short trips, especially if you live in a large metro area where traffic is an issue. Its a waste of time, money, and will save you a lot of headache driving in big city traffic.
However, if you live in a more rural or less populated area, public transport is often times either non-existent or completely impractical.
My point being, making a call for public transport is only a legitimate argument in areas and social situations that allow for it. Kind of hard to expect Joe Iowa farmer to ride a bus, and what about Bob the contractor or construction worker? Not exactly doable for him no matter where he lives. Can't take all the tools he will need on a bus or subway.
Of course, but public transport is practically non-existing in the US compared to europe and especially China.
In China you can take a high speed train from Shanghai to Beijing ( 1 318 km) using 4 hours. A distance that is comparable to NYC-Chicago (1 270 km).
The government paid for the line, but since the service (high speed train) is not profittable and demands a large investment cost ($32 billion dollar) it wil not happen in a market with "free competition" without state controll.
Even Russia are building electric trains in Siberia a area that is rural. They can do it because they state have large incomes (oil,gas) that privat persons would have in the US:
That will make US missing a lot of good/welfare services that no-one wants to start up because it is not profittable and has a large investment cost.
Wouldnt it be great to take a high speed train from Chicago to NY that takes about 4 hours instead of a plane using about the same time for city-center to city-center?
The train line itself will cause a lot of benefits eg. transport of freights. The benefits having a electric train is large, youll get higher top speed, faster accelaration, larger capacity. No diesel train can compete with that without having an engine the size of a ship-motor.
But since you have a free market economy you will lack good services like that. And if you get sick you will have to pay for it, I once read about a person that got a snke-bite in the US he had to pay 140.000$ in a mixed economy system he would have paid 0.
But with Obama youre on the right track he is a sensible man, with a more pragmatic wiev on things than hes predecessor George Bush.
