Better-off people have the opportunity to get work experience from a job that doesn’t necessarily pay a living wage, or to work part-time (with the associated pay cut) while getting an education, because they have savings they can live off of or relatives who will help them with living expenses (generally without charging interest for the loan, as a bank or other commercial lender would do). Poor people don’t have that option- they have to get a job that pays their living expenses right now.
Quitting smoking is hard for anyone, AIUI. There have been many threads in which Dopers talk about the difficulties they have encountered in quitting smoking. I suspect it’s even harder if you don’t have health insurance- you don’t have access to some of the methods of quitting smoking that people who do have health insurance and prescription drug coverage do.
Unfortunately for people who want to go with this option, Civics hold their value pretty well, so a slightly-used Civic isn’t much cheaper than a new one.
I know this because I have a three-year-old Civic, and Mr. Neville recently had to look up its value as part of determining our assets for getting a mortgage. We found out that it’s still worth (at retail, which is, for whatever reason, what the bank wanted to know) almost as much as it was new. I would assume that something similar would be the case for other cars known for reliability.
And Murphy’s Law applies here- cars seem to know when it’s a bad time financially speaking, and choose then to require expensive repairs. For most people, a car isn’t something they can do without for a few weeks or months while they scrape together the money for repairs, either- they need it to get to work or the grocery store or to any education or training they are taking. And poor people are less likely than better-off people to have jobs where they can take a few hours or days off because their car is acting up.
Of course they should do something. But we as a society should also be doing something to help them deal with some of the very real difficulties they will encounter in doing so. Telling poor people that they need to go out and get an education isn’t enough to solve the problem. There are things that we as a society could do about a lot of the problems that create the cycle of poverty, if we wanted to.
There are a fair number of poor people who are not stupid (there are, of course, some who are). The ones who are not stupid probably know that they would be better off if they got some education or training, got a better job, and so on. But it’s difficult to do those things while working long hours, spending a lot of time commuting, and living paycheck-to-paycheck. I suspect that most better-off people, if they suddenly woke up tomorrow as a poor person, couldn’t or wouldn’t do it.
Don’t underestimate the psychological and emotional effects of constantly hearing that you must be poor because you’re stupid, lazy, and inferior, either. It’s not easy for someone who is being constantly bombarded with the message that they’re not good enough to think that they could make themselves better if they wanted to.
