Success isn't about beating everyone else, it's about realising your own dream, about pushing yourself to your limits and breaking through them, it's about education, advancement, self-belief - all things that are inherent to you only. Successful people don't seek to keep industry players down or to dissuade the younger generation from even bothering, you'll find that the most successful people are those who are willing to share - willing to give away some of their wisdom to actually help others achieve their goals.
The energy spent in keeping someone else down is far better spent on oneself - educating, improving, challenging yourself, creating bigger goals and striving to achieve them - building on your achievements and the groundwork you've created to build something phenomenal.
Next time you worry about what the person next to you is doing, take a look at your own work and identify where you can build on it - you better believe that's exactly what they'll be doing and if not, they're not the kind of people that will find the success you're working towards so their progress or regress is of no concern. Stay focused, keep working, keep building and share what you've learned because you never know how valuable it can be until you try.
