Common people have no money in their pocket because they are moving their circle and their spending are more and they have no money on which they depends.
A common man is usually also a victim of things like the debt trap, where no matter how hard he works, the interest is always higher than what he earns and the capital loan remains the same or gets bigger over time.
The food prices are more and people are dependent on the income only and they have no side income and they have no savings in their pocket.
And that's why it's very important to have multiple earners in any household, and if possible, have multiple sources of income. One guy earning for a family of 4 will never suffice. Once you have multiple earners, you realize things suddenly get much easier, not just because of the extra income but once more people start earning, they start valuing money more and understand the value of saving. One who is not earning usually doesn't realize the importance of money.
