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?
This is a classic case of inflation, but this situation can be traced to the fact that the person earning the $500, moved probably to a new location after you started earning $1,000. If the person had stayed in the same location after receiving that $1,000 or even moving to a more remote place that can be more affordable, then it would have helped a situation like this.
In answering your question, you are not getting richer because the amount you earn is being quenched by inflation, so you will have to look for a way to manage the situation, is either you cut down on unnecessary things that you don't need to buy, you stay in a location that is more affordable for you and your family, and you should probably look for an alternative source of income to support what you are earning.
