Exactly. You wont be gaining much if you are just sitting around one chair and doing nothing. The world itself is becoming way more expensive than anything now. Whether it is fuel, plastic chair or street food, I have seen them changing cents to cents every now and then. However what we dont realise is that these cents have piled up so much now that they have added multi dollar value to every thing.

The point is simple, our salary or income is not increasing at that same rate at which the expenses are growing. If we wanna have proper bank balance, then we need to have income which will balance out the expenses first and then we start saving huge amount. Thats why have multiple incomes, fill the accounts until everything looks way way cheaper.
