I think Sam's dad said he had 80 pounds per week -- there's a lot of difference between that and 130.
So, your veg patch, then. On a subsistence level income, can you afford seeds, fertilizer, allotment rent (if no garden), tools... it's ok if you have these things already but so many don't.
Cooking something for an hour on an electric cooker is hugely expensive, much more expensive than an hour's television. If you are on a key meter the cost of cooking can be astronomical.
It's tru I don't mind walking a mile or two with my shopping sometimes. But I'm bloody glad I don't have to do it every single time. Share a taxi what planet is this, when we are talking about subsistence level incomes.
Being poor is a bloody struggle, an endless, tiring debilitating struggle. Poor people have massive levels of mental illness, most commonly depression, that they wouldn't have if they weren't poor. It's all very well for those of us who are comfortable to go on and on about poor people making bad choices and choosing to live in squalor, but most people know from their own lives how hard it is to motivate yourself and keep active when you are down.
Imagine then that you have (probably undiagnosed) long term depression, feel that nothing can ever change in your life, that everything is stacked against you. Even though making that nutritious bowl of soup, washing the floor and getting out to dig the vegetable patch would probably help you feel better, for some people that will be a mountain to climb.
Of course there are some people who would always make bad choices. But there's such a lack of imagination here about what it really means to live at these income levels day after day, week after week, year after year, generation after generation.
