Agreed. Just look at the amount of listed companies now compared with 15 years ago. It's a lot less. Still, if you hold quality shares that makes more money outside the borders of this country then inside and you have a 75 year view you're safe. ;-)
Sure but over 60% of the TOPI value is foreign. Apparently over 60% of revenue earned on our market is too. If this chart were to be USD adjusted, it would look a lot flatter. That said, however, if you had invested in companies that were "emmigrating" - you would have outperformed this chart.
