But if you know how to save and invest then you will surely prevent having work that is not good to other people.
Money is the root of all evil sometimes because you can buy other people's dignity if they really want a certain money just to survive.
Those are people who don't know other options how to earn decent money. Or sometimes they will choose that route because for them, they have no other option and that's the only option that is available at their disposal. But if you want to earn a decent living, you can always find one, even if you will not be earning that much. If there's a will, there's a way, as the saying goes. Not all poor people will go to this route, there are some that can emerge successful despite being challenged with financial situation.
