Who makes more money? A doctor earning $5,000 a day or a salesman who make $.01 cents a day, which doubles every day for 30 days?
Be careful when figuring this one out. It may suprise you. The salesman will make .01 on day 1, then .02 on day 2, then .04 on day 3 and so on.

$150,000.
However, if the salesman stops earning money after a month, and the doctor continues to earn money over a 30 year career, the doctor will end up with more(54.8 million)

A doctor earning $5000 a day would earn $150,000 over thirty days. I suppose we assume his earnings are after malpractice premiums are paid. I notice he gets paid seven days a week, and maybe he comes in Sunday, but I think I saw him on the golf course on Wednesday. For the salesman, we could get a calculator and calculate two to the power of thirty. On his last day he will earn 2 to the twenty ninth, and when you add in the previous days it will be about 2 to the thirtieth power all together. Its more interesting to note that two to the thirtieth is two to the tenth power cubed, and two to the tenth is 1024, or slightly over 1000. Two to the thirtieth is slightly over 1000*1000*1000, or one billion pennies, or ten million dollars.
So the salesman makes more money in theory. In practice he probably paid $300 to get involved in something promising geometrically increasing commissions. I doubt he'll get anything.

Your explanation is right, but there is an addition error. The total should be about 10.7 million.
