That's practically a tautological argument though. People who don't like expending a lot of effort on certain things will necessarily have less success at performing said things. And people will also necessarily have different preferences on how to spend their time and energy, and different amounts of time and energy as well. Would also like to point out that "sitting on a beach forever" is not the negation of spending all your time an energy on solving the problems that the capitalist economy rewards. There's plenty of people out there who have a passion for things that aren't expected to earn money, but for whom the best option for actually making money is something that's quite boring.
