It is good to encourage people to save money and invest them, but 8 out of 10 people out there don't earn enough to gather so much capital to live off it.
In general, you are right, but many people on this site do earn enough. Engineers have some of the highest paying "normal person" jobs out there. If we can't save and invest for the future, who can?
Agreed. And if more high income professionals pursued this path, it would tip the balance of power in the workforce away from employers. That's a win for all except those at the top.
