The thing is that, unless these changes you’ve mentioned, which I happen to agree with, occur in the lifetime of the masses–their lives, and the lives of their children or grandchildren will not change for the better–then they’ll be over–and that’s the sad reality of making political promises that cannot possibly come true in a meaningful period of time.
Therefore, since we don’t believe we can change any meaningful financial aspects of our world for the better in our lifetimes, we’re doing everything we can to protect what we have for ourselves and our children for the time we all have left.
I’d also like to add, that, whether the “punishing the successful” concept is true or not, I have a SIL who has been buying up property with the intention of renting it out (for next to nothing) to all of the kids in the family after college–should they need these homes–and is planning to bankroll them, as necessary, to help them survive in the world. Basically, people will either survive, or they won’t–no “meme” about it.
