Maybe people who are bad at pre-planning are also potentially poor parents.

Women's contraceptives in the states require a prescription. Which requires a doctor's appointment + insurance. If you are poor or live with strict parents (ironically), you are much less likely to seek them out.

Condoms are their own bag of worms. I think there are cultural differences in condom use here, as well as the same problem with them being a cost. This doesn't even touch on men being shady with stealthing and pressure.

On the other hand, the abortion clinic requires only an appointment and a way to get there.

In the 1980s, condoms were "behind the counter" things you had to ask for and suffer the critical eye of the pharmacy worker (at least in small town USA).

It's no wonder we had so many teen pregnancies.

Why not both

one can be prevented by the other

No contraceptive method is 100% effective.

hence "can be"

We don’t need airbags because injury can be prevented by seatbelts.

The "don't need" part is a fictitious part you inserted into the argument and not a claim I made.

Injury "can be" prevented by seatbelts, that is a valid claim.

I don't know what else you could have meant when you answered the question "Why not both" with "one can be prevented by the other".

The implied meaning is: "Not both because one can be prevented by the other".

Hence "both".

not prevented… (trust me :)) but best we can do!!

They probably aren’t using them.
