Poverty is not a choice but a compulsion. Those who are poor are not poor by choice, but they are poor because they don't have a way out of that state. You may say that getting born poor is not your mistake but dying poor is your mistake, but that is only for saying; such phrases are only good in theory, but in practical life, things are not that easy to manage. You can't just get up one day and decide to not stay poor anymore and achieve everything. You need a base to get started, and if you were born and raised in a poor society, you will barely have that.
A lot of poor people work extremely hard, they do whatever they can so that they can have a better life, and give their families a better future, but at the end of the day, they can't do much since they lack both the resources and opportunities, and you can't make good money if you don't have any of the two. If you don't have resources, you should at least get some opportunity that you can use but if you also don't get that, you won't be able to go far no matter how hard you try.
Everyone is born poor - even if they are born into a rich family. By poor I mean poor in knowledge rather than wealth - so all classes are basically the same. Things will change because of the differences in the way and method of education taken - the rich are more likely to become rich because of privilege, while the poor remain with their poor mentality. Although each of us has the opportunity to change - but not all of us are ready for the risk. There are many poor people whose children become successful - they can improve their family's status and that is a proud achievement.
What we need to admit together is - nothing is impossible in this world, unless we never try. Take risks - do your best and never give up even if we fall many times. Great stories are not born from those who have everything - but from pioneers who did not get anything from their parents.
