If you want to be rich sell to rich kids.
Like what exactly? Kill this idea because that's not true. If you want to be rich, sell to the poor but what you will selling must be a need. Something you know they need to use atleast once a day, you will see how very demanding your business will boom if it's become successful.
Now let's talk about homeless people in USA and CANADA.
The world don't know that many of those homeless people are from the rich families.
Those homeless kids are only from rich families, some are from average families and the rest from poor families especially the ones that can't afford 3 square meals and you what cause some of this is because they are disobedient kids that abused western life just because they think their families can't touch them or scold them, in Africa we hardly see homeless kids because the parent are meant to instill descipline into you in many ways.
By the way, your topic is misleading. It doesn't portray what you are trying to communicate. I was thinking it's like spending extravagantly will lead to broke life.
