With $3m in super, you could draw $100k/year and assuming 5% growth you'd have over $3.5m after 10 years:

Year,Starting Balance,Withdrawal,Interest Earned (5%),Year-End Balance  
1,"$3,000,000","−$100,000","+$145,000","$3,045,000"  
2,"$3,045,000","−$100,000","+$147,250","$3,092,250"  
3,"$3,092,250","−$100,000","+$149,613","$3,141,863"  
4,"$3,141,863","−$100,000","+$152,093","$3,193,956"  
5,"$3,193,956","−$100,000","+$154,698","$3,248,653"  
6,"$3,248,653","−$100,000","+$157,433","$3,306,086"  
7,"$3,306,086","−$100,000","+$160,304","$3,366,390"  
8,"$3,366,390","−$100,000","+$163,320","$3,429,710"  
9,"$3,429,710","−$100,000","+$166,485","$3,496,195"  
10,"$3,496,195","−$100,000","+$169,810","$3,566,005"  

"But $100k won't be enough in ten years!" I hear you say. Ok, let's give ourselves a 10% pay-rise every 10 years.

Year Range,Annual Withdrawal,Year-End Balance (End of Decade)  
Years 1–10,"$100,000.00","$3,566,005"  
Years 11–20,"$110,000.00","$4,355,900"  
Years 21–30,"$121,000.00","$5,497,281"  
Years 31–40,"$133,100.00","$7,196,668"  

With a starting fund of $3m, and a 10% payrise every decade, after 40 years we have over $7m in our super fund. Now, what happens to our poor rich person who needs to pay 30% on growth above $3m?

Year,Annual Withdrawal,Ending Balance,Annual Tax Paid
1,"$100,000","$3,045,000",$0
10,"$110,000","$3,472,749","~$6,144"
20,"$133,100","$3,871,911","~$12,048"
30,"$161,051","$4,110,378","~$15,716"
40,"$194,872","**$4,052,857**","~$15,271"

Instead of ending up with $7m after 40 years, this poor individual now only has $4m after 40 years.

As I said, I really wish I had this problem!
