Why don't people generally save more of their income?
A person who always saves and appropriately invests 20% of their income can expect to have a secure retirement. If you start early enough, you don't need anything close to 20%. Now, there are many good reasons to save for things other than just retirement, of course. You say that you can save 80% of your income, and you expect most people could save at least 50% without problems. That's just unrealistic for most people. Taxes, rent (or mortgage payments), utilities, food, and other such mandatory expenses take far more than 50% of your income. Most people simply don't have the ability to save (or invest) 50% of their income. Or even 25% of their income.
