Earning more money and being financially comfortable are two different situation in the present day global economy. that you are earning more than your previous salary doesn't always mean you're financially better off.
In reality, Someone can move from earning $500 to $1,000 a month and still feel like nothing really changed. the reason in most cases is that Rent also increases, food costs more, transportation gets more expensive, and suddenly that extra $500 doesn't feel like much anymore.
It begs the question, is increased income really a good measure of financial progress?
If your income keeps increasing but the things you need also keeps becoming more expensive, are you getting richer, or you're simply earning more money to maintain the same lifestyle?
Increased income is never a good measure of financial progress because the country can have high inflation and your salary can increase every month, but if the purchasing power of your salary decreases even though it grows in numbers, it means that you are doing badly.
Today, businesses increase the price of their products and services while employees continue working on the same old salary. In order to survive, many people have to work extra hours or a second job. Today, we really are working harder to maintain a worse lifestyle than we had because, by working more, you don't have time.
