So much to unpack in this comment to begin with:
1. No, capitalism does not lead to greed, greed is a human condition that exists in all socio-political systems.
2. "Isn't there a system that works for everyone instead of having such a disparity between rich and poor?" Unlikely. The best human kind has achieved thus far is a system where the overall economy is strong, and the poor are less poor because of it. That is capitalism.
3. "Today in the United States, most people are living paycheck to paycheck." Same as it ever was. No economic data supports real wages being lower now than they were in the past.
4. "More than 50% of americans do not own a home." This has a lot more to do with the shortage of housing in big cities due to regulations, than it does with an actual decrease in economic power.
5. "It is also predicted that the majority of jobs will be replaced by robots." In the history of automation, automation has never net decreased the number of jobs. However, there is an argument that this time is different.
6. "College graduates are in hundreds of thousands of dollars of debt." A college degree pays out a million dollars more over a high school diploma in lifetime earnings. Most college graduates are debt free by age 30. Furthermore most of the "college debt" is held by med students and law students who do get high paying jobs to pay back their debt.
7. "Many young people do not have a lot of hope for the future, because they have been lied to by being told you can achieve big things if you work hard."
When everyone is special, no one is.
