I don't know if you're trolling or not but I'll answer.
First off, you get to keep far less of your $28-30K per month than you think. Jan, Apr, Jun, and Sept are when quarterly taxes are due. Best plan on making $40K tax payments in those months. Should you fail to do so, the penalty and interest will certainly open your eyes come April of next year.
Second, when you make the kind of money you're talking about, you tend to buy more expensive items with higher maintenance costs. Your car insurance is higher (and the car requires premium gas), your house is larger and requires more furniture, your home insurance is higher, your heating/cooling bills are higher, etc. Basically, everything costs more than it does for you now.
Honestly, you're in a bad tax bracket. You make enough to be taxed to high heaven but not enough to have the proper tax attorneys to keep you from paying a lot in taxes.
My free advice is....don't change your living standard and save the cash. Do that for 2 years before you begin to live like you're making that kind of money. If you can delay it even further, keep saving. There really isn't much of a need to spend more than $60K/year (in my opinion).
