How can people afford cars?

folding bike there, or walking-its free.

accepted,

Maybe if you're close to the station

but if you have a meeting it can be booked in advance by Tiffany in reception. No doubt you need to be dedicated to get into training it everywhere,
and every journey needs taking into account. It makes me weep how the fares system fucks everyone in the ass to the benefit of the fat cats.

Depends how far in advance your meeting is does it not?
Don't get me wrong as I said I like trains for long journeys but their potential for car replacement is massively over stated. They can be good for commuting to work if you work in a town center, good for center to center travel in many cases but they are not a car replacement they are just another form of transport and for some journeys they are better but for many they are not. and frequently more expensive.

Better jobs?

better paid jobs.
