The difference in wealth will be the same. You can think of money as distance. Your income is speed. If you have travelled 100 miles from the start location, you're 100 miles away from anyone who is just now starting. That doesn't change if some guy comes in and says "no, we're changing the units of measure. You're actually just 10 malms away from the start."
So now the new guys are only 10 malms from your current location. But it will take them every bit as long to catch up to you. It matters nothing that 10 is a a smaller number than 100. The distance is not changed. Only the number attached to it.
