"Scared pussies" survive, but don't do anything. What we need is a good social safety net so people are confident that when they take a risk and fail, it doesn't mean their life ends.
Oh sure, like you can just do that if you're out of money. (/sarcasm) It costs money and time to get a passport, fly out, have a destination that will accept you, figure out security for yourself, etc. Plus, you're making it harder for the existing people there to keep prices low.
If you have a bunch of money lying around, sure. But most people are pretty decently in debt or at best just outright poor when they run into issues like that.
Depends on your situation. If you have family and friends maybe, but lots of people don't survive and you don't see them. Healthcare, housing, food, etc. is mostly tied to employment or lots of money. People don't have time or energy to figure out any alternatives if they exist, and face eviction and starvation if they don't, which is a whole new world of not being able to survive. We see lots of drug abuse, theft, suicide, and similar things precisely because there is no safety net.
Look, I don't have the capacity to precisely answer your question. But if it is rare that people are failing through the cracks after taking a risk that's all the more reason to do it. It should be cheap.
