It wasn't easy to get started 40 years ago, either. It was never easy, and it still isn't, but I constantly hear its-not-like-it-used-to-be as an excuse. If that were true, then nobody these days would ever "make it." But some do: those who are determined and ambitious (and fortunate enough to be of sound mind and body). No, we did not all have rich parents or go to Harvard or know important people. No, we did not all see the path clearly before we started, or even in the middle sometimes. Yes, it seemed impossible at times, but no, it's not.
You may be indulging in selective memory. Higher education was far cheaper in the 60s and 70s than it is now. The student loan situation is far worse than it was. And employment ops were more numerous then than now.
This isn't about bootstrapping. Even the determined and ambitious find the going rough. Those who are neither determined nor ambitious are pretty much doomed.
