I want bullet trains
The first word, I, is wrong, when the preceeding sentence is we. Why is a fast train preferred over a slow train, why the rush? Ask your average sporty cyclist, above 16kph(10mph) the effort needed to maintain speed or accelerate increases exponentially due to wind resistance. Same for any vehicle, land, sea, air. On whose clock are you running? The capitalist clock where time is money and money is time?
What you want and what society needs may be in contradiction. Who decides what society needs? Popular vote, majority rule, experts, politicans, scientists, … everyone?
We most definitely do not need fast trains, planes, or automobiles. The reason they are available is because they are profitable to someone(s).
The world better slow down or it is burning itself up
you have spoken like a true “communist” … ??
