Except for those who are brain damaged, there are no stupid people.
Only lazy people and those who are willfully stupid (like Liberals) are what we normally call stupid.
So you think there will be enough jobs in the future for those who are not of the entitlement mentality and willing to work on whatever field they are capable of working on? And that everyone who wants to support themselves on an income will be able to do it?
And btw, change is not always inevitable, people who are determined to fight change can always do it. Some countries do it all the time and America in some ways has learned how to fight certain kinds of changes too. If the fears I raised are true, Americans may already be looking for ways to effectively block those changes too if they believe it will do much more harm than good.
