Considering that out of the ~8 billion population of earth majority of them are living paycheck to paycheck (specially in this recession+inflation infested world), they kinda have to spend their money as fast as they receive it because they've already stretched their last paycheck as far as they could have.
Life is very tough, especially if you don't have any heritage. I was thinking yesterday about the fact that with my income, I probably in the 5% of the local population, which means that among 100 people standing, I'm in the top 5 but even my salary isn't much and I can't stop thinking about how to increase my revenue. At the same time I think that life isn't very hard, there are many possibilities. You can't achieve success if you work for someone else but if you manage to break and create your own business, then life becomes much easier because you pay low salaries to your employees while you get all the profit. It's like, being a slave is bad but if you manage to become king, then having slaves is very good.
