Kimmio, this thread is about MADD to my knowledge; however, if you wish to speak regarding poverty.
Per the stats on poverty, there are 85.6% of the population of disabled people who do not live below the poverty line, and so, though poverty is a factor, it is not the only factor. In addition, just because you are poor, does not mean that you would not want some form of an advanced directive and clear wishes. In fact, you may wish to be more intentional about documenting it, as per your earlier comments, you could not expect those who would fit into the category to act based on your wishes:
These stats come from the Council of Canadians with disabilities:

Disability and Poverty
The overall poverty rate for Canadian adults was 10.5% in 2006, comprising 2.6 million people. The Conference Board of Canada recently found that Canada ranks 15th out of 17 countries in terms of poverty among working-age people and gave Canada a 'D' rating on that basis.[
