The tone of this is a little hard to read, so forgive me if I've misread anything.
I mostly agree with the other changes, except for increasing pay as a means of eliminating the motivation to play games. If there's one thing we've seen play out over and over, it's that excesses and greed just beget more greed. Look at the number of executives, financial managers, and politicians who already had vast wealth yet STILL engage in shenanigans. Furthermore, the job of legislating is an elected one, which means it will always go to those who are best able to convince the most people to vote for them (frequently by promises and pandering), not those who will do the best job. Now, I don't think legislators should get pauper's pay, but I also think we should do what we can to limit it's use as a career path for power and wealth.
I have no problems with capitalism. If the market has healthy competition and the referees (regulations and the courts) are fair and transparent, capitalism is good. Unfortunately, many of those elements have gotten worse in recent decades. We regulate more than ever, but it's the small businesses who suffer the burden and have no real voice in DC.
Capitalism done right means that I'm not upset by Wal-Mart's success, as it's kept in check by other companies like Amazon and Target. If you think anybody is invincible, take a look at what happened to Sears, K-Mart, and Toys-R-Us. Capitalism done wrong means that big companies use regulations and unfair referees to keep out competition. The power wielded by FAANG today dwarfs anything Microsoft ever had.
