I think that is a good strategy. However much money you have, downplay it, unless you make so little already that you'd scare away potentially good matches, in which case you should just tell the truth. It's easy to attract women when they think you're rich (rightly or wrongly), but it's also counter-productive.
An even better strategy RJS:
Unless and until you get real serious/engaged to a lady, don't even mention money. Tell her nothing about your income and lifestyle. Be vague about your occupation if you have to.
If she brings the subject of money up, ignore her. If she keeps pushing the issue, dump her.
