Ramit Sethi won't pay advisors a percentage of his assets, but he does pay them for specific work like reviewing his asset allocation and spotting risks when his portfolio is large or complex. Most people can manage their own investments.
I'm going to tell you it straight. I would never pay a percentage of assets under management. I would and have happily paid a financial advisor to help me out, to take a second look at my asset allocation, to show me if I'm not considering certain risks. I think a lot of people can manage their own investments on their own. In fact, I'm going to show you in a minute. But if you have a complicated situation or a large portfolio, you're getting closer to retirement, sure, it can be helpful to work with a professional.
