If you have 1000$ to invest and it appreciated 7%, that made you a 70$ profit, which is not much from a coat of living perspective. If you had 1,000,000$ to invest, that gives you 70,000$ profit, which is pretty good at covering living expenses, bit not leaving you much else. Now if you have 10,000,000$ to invest that yields 700,000$ in profit, that is marginally way more and covers living expenses, plus gives you room to invest in other actives, thus improving your chance to grow your wealth.
