Point by point.
I am not handicapped, stupid, lazy or any number of other very human things that you are ignoring. I worked my ASS off for years and still could rarely afford any amenities. Hell, I frequently had to choose between food and paying bills. I know what it is to live frugally and survive, but not be able to afford things most americans take for granted -- that was without any of the problems you so quickly dismiss. What if any ONE of them had happened to me? Do you really think it's that simple?
You chose the wrong profession if you wanted to make money. It was something to do with landscaping right? You probably chose it because you love it. But if not struggling and not being poor was your goal, you would have chosen a better profession. You are very smart and very pretty, a very good combination to have. I know you could easily make money if that's what you wanted!
Why do they need help? People need to learn how to sink or swim. I had to.
My point was that their family needs to work hard in able to support them. And yes, people can work and be caregivers. I've seen it. Nobody ever said it was easy, but it's possible.
I was fairly dirt poor too (steel mill family), and I'm proud of me for making it. Hell, I'm proud of you too, if you did it. However, this does not on any level mean that everyone else can do what we did. It's rude and abusively myopic to assume such a thing.
Yes, anybody can do it! That's the point! But when know they have a safety net, they don't try so hard.
Do, or do not, there is no try
