Do reddit users have too much power?

Does Ellen Pao's departure from reddit set a precedent that gives the reddit community too much power over the company?

 
No, it does not set a precedent that gives the reddit community too much power over the company. First, there is an implicit assumption in this question, that it was the reddit community alone who caused Ellen Pao's departure. That hasn't been established, and it is probably unknowable, other than through rumors. 

See Did Ellen Pao get fired from reddit? quoting Sam Altman saying that it was mutually agreed upon for her to depart.

According to Ellen Pao herself, she resigned. There was tremendous pressure for her to step down from the reddit userbase, including a petition that reached 200k+ signatures: Ellen K. Pao: Step down as CEO of Reddit Inc.

When I asked her directly if she was fired, Pao laughed and said, “Thanks for getting right to the point,” but again underscored that she resigned. Reddit board member and Y Combinator head Sam Altman answered more definitively about whether she was ousted: “No.”

How does the public react when political figures state that millions of illegals workers do not compete with Americans for jobs in the US?

Do people get mad when political figures tell them that a major economic trend, like millions of illegal workers competing for jobs, is not happening? 

People do not have a chance to get angry because the mainstream media refuses to report what entities such as the Federal Reserve publish, regarding the negative effects of immigration on youth employment in the United States.

 
This is the abstract of a 2012 research paper by a Federal Reserve economist, "The Impact of Low-Skilled Immigration on the Youth Labor Market" jstor.org/stable/10.1086/662073

The employment to population rate of high school–aged youth has fallen by about 20 percentage points since the late 1980s. One potential explanation is increased competition from substitutable labor, such as immigrants. I demonstrate that the increase in the population of less educated immigrants has had a considerably more negative effect on employment outcomes for native youth than for native adults. At least two factors are at work: there is greater overlap between the jobs that youth and less educated adult immigrants traditionally do, and youth labor supply appears more responsive to immigration-induced wage changes.

The actual Federal Reserve publication was released the year prior, see Smith, Christopher L. 2011. “Polarization, Immigration, Education: What’s Behind the Dramatic Decline in Youth Employment?” Federal Reserve Board of Governors Finance and Economics Discussion Series 2011-41.

Should I work for an exotic tech startup company?

My answer to Is it worth it to work for companies that provide in-flight Wi-Fi like Gogo, OnAir, Row44, etc.?

You don't need to worry about it until you graduate with your degree. It would be a good idea to intern for one of the inflight Wi-Fi companies while you are still in school, as that should help you make a more informed decision.

If you are married and especially, if you are married and have children, you should work for an established company right out of school, as the medical benefits, compensation, and workplace stability will be better. Even if you are not married with children, you should be careful about getting your first job at a small, young company whose primary business could be derailed by regulatory issues.

It is possible that one or more of these companies developing in-flight Wi-Fi services could be bought out by Juniper, Cisco, or even a major airline.  The scenario of the airline purchase is interesting and has precedents, e.g. American Airlines purchased SABRE. Even if such an event should occur, I don't know if it would have any benefit to you as employee rather than a founder/equity owner.

Another reason to work for Juniper or Cisco for a few years, when you first graduate, is that it will increase your credibility and perceived value to future employers. Transitioning from a big company that is well-established in its industry to a start-up is easier to do than vice-versa. My first job out of school was at an innovative small company; I left after two years to work for IBM. I wish I could have done it the other way around.

Why are dropouts like Elon Musk and Steve Jobs more successful than college graduates?

Why are dropouts like Elon Musk and Steve Jobs more successful than college graduates? How do they get the platform to rise?

You didn't mention Bill Gates, but he is often cited as an example of a successful college dropout. That is more myth than fact. This is what Bill Gates said about his college education at Harvard:

It is strange to call me a college drop out in all but the most literal sense. I went for three years and took enough courses to graduate...So I am kind of a failure as a drop out.

--Timeline: Bill Gates 

One theory that I've read about, especially in the context of the electronic payments industry, is that college drop outs have only two choices: get a low-paying job, or risk the realities of forming a new business. Necessity forces them into entrepreneurship.

Is the EU's Schengen treaty unique?

Yes, there are other Schengen-type treaties around the world? Some Schengen-like treaties in the western hemisphere.

North America 

At various times, the United States and Canada have enjoyed a functional Schengen treaty arrangement, even though it was not formalized. US citizens did not require a passport or visa, nor pay any fee to travel to or from Canada. The same was true for Canadian citizens traveling to the US. This protocol was observed for automobile and passenger rail transit, although I am uncertain about air travel.

 
I was an enthusiastic novice international traveler in the 1990's. I was eager to get as many stamps in my passport, from as many different countries as possible. On a drive from Seattle to Vancouver, I had my passport with me, although it wasn't necessary. The Canadian immigration control officer was amused at my request for a stamp of entry, and eventually dug one out.
