Investors are entitled to attractive returns
All investing is risk-taking. More often than not, the risk is that you will not receive back the amount that you invested. This could be because a business struggles. Or because your investments could lose value due to investors hoarding their assets in fear of global financial instability—much as they did towards the end of 2008 and 2009. Or, this could be because inflation cuts into the value of your capital over time.
Investors are entitled to attractive returns as an incentive to carry these risks. Without the promise of return, no one would invest. Without investment, we would have little growth.
