First of all, I go like talk say Bitcoin is not government, to make life either easy or hard for the less privilege of any country, or rather is Bitcoin a reward to sympathize those who may have experience tough times in the economy, but rather Bitcoin is just a mere decentralized digital currency, whose duty is to enable seamless inter-continental easy and fast transactions between two or more parties. So the question about "how can a digital currency make sure the less privilege fit afford to purchase am" sounds somehow to my hear, because what I expected you to ask is "how can the less privilege invest in Bitcoin with the small capital they have got" or "what are the opportunities in Bitcoin that less privileges could take advantage of", and not this. So However, I will suggest you go get a job, and then start to invest in Bitcoin with the little capital you can afford either monthly or weekly.
