My point is that some people are unable to move to a job without a little financial help from somewhere. I also feel it unrealistic to expect a bus+walking as transportation to anywhere in the US for poor people, not every town of any size is served by a bus system.
Given that the interior of America was settled in the 18th-19th centuries, mostly by poor people with no access to gov't or any assistance, it is not so impossible as some might think.
I suspect a lot of this is an unwillingness to see folk live below some first-world standard of living. On one end you get the "It is unrealistic to expect a poor person to move and make a new life for themselves without help." At the other end is the dang near
outlawing of poverty. By that I mean, making illegal the actions one must take and the conditions one must endure while poor.
For example:
Barely making it as a family of four (mom, dad, 2x young kids), can afford only Dad's regular-cab pickup he uses for work. After work, family goes to the grocery store because Dad got paid (Yay!). Well, Dad is violating at least two laws. First, every kid needs a booster seat. Thing is, can't get 4-across seating, 2 of them boosters, in any pickup I know. Also, kiddos not allowed to sit in the front seat. So, after pulling in a fat $800, heading to the grocery store, and thinking about new shoes for the kids, they get pulled over and get $800 in fines for the above listed infractions. ($200/each is the going rate in Texas, IIRC. Gotta crack down on those scofflaws[1].)
[1] Unless they are illegal aliens. Nobody expects them to comply with or pay fines on such laws.
