A lot of it has to do with the company you work for-- different corporate compensation strategies will leave you with differing amounts of savable income. So change jobs if you aren't making progress.

Above all: Save regularly and invest in some way that will bring the power of compound interest. Live below your means, never withdraw the money, always add to it. After a reasonable amount of time, you will find yourself relatively 'wealthy', no matter how much or how little you are accustomed to earning.

Good luck!
