In my belief, America can achieve its full potential once everyone learns to let go of the post World War sentiments - political correctness, need for ostensible selflessness, fairness of outcome, independence, anti-monarchs/empires/colonies, and any other leftist bullshit.
Take a look at Saudi Arabia - a wildly successful nation with one of the most profitable state-owned enterprises in the world, crime rates near zero, highly efficient society, no protests, homosexuals, few liberals, etc. Religion has a strong influence on everyone's daily lives, and empirical evidence has supported the claim that this religious innfluence actually promotes the right values.
Then you look back at America - cesspool of liberals, historically-suppressed minorities who now have a voice, pop culture, Hollywood, and just general plebes enamored with entitlement and victim mentality. We have massive pricing issues, uncontrollable rent in major cities (yet people continue to build luxury towers instead of affordable housing), a shitty education system that promotes reverse discriminantion - basically giant collective of leftist circlejerk and a cesspool for social justice warrior, feminist dogma, giving preferential treatment to gays, lesbians, transgenders and bisexuals, poor people, and minorities/leftists who may not actually be qualified. I can go on an on, but the point is, this nation is just one giant clusterfuck.
One solution is for the government to be much more liberal in its administration of capital punishment, banishments/exile, deportations, detainments, and possibly, establishment of labor camps. While it may not, in today's liberal, leftist, and politically correct society, seem "ethical," or the "right thing to do," we can greatly increase efficiency in our society. In the South, all those people inn ghetto areas spending their days and nights smoking crack, listening to hip-hop, and lavishing themselves in racial grievances and victim mentality, could actually contribute some tangible benefits to society by performing simple jobs in a labor facility (assembling cars, building highways, dams, bridges, and other infrastructure, chopping down trees, etc.); this way, they don't have to go through the bullshit, leftist job market, or encounter HR.
Another possibility is capital punishment. Ethics aside, capital punishment is simple in both its nature and execution. Just think for a second - how many people have you met whom you think contributes nothing to society, but hog our scarce resources? Whether its old people, homeless people, poor people, people who are out of the labor force (read: discouraged workers only), minorities who spend their lives relying on victim mentality, SJWs, or the politically-illiterate, capital punishment presents a simple yet efficient modus operandi of "cleaning" out our society, and in the process, great increasing efficiency in daily operations. Remember, killing one man is a tragedy, but when scale increases into the millions, its much easier to think of it as a statistic, nothing more.
Less "cruel" (if that's how you want to think about it) alternatives include mass deportations and declaring people persona non grata. Most Mexican-Americans love to spend their living hours bitching and moaning about how shitty a place America is towards minorities, how much they are suppressed in their daily lives, and how "racist" immigration control - why not just go back to where you came from?? (considering more than 50% of illegal immigrants in the US are Mexican). Similar argument for banishing people - highly effective for suppressing criminals (if we don't just kill them), political enemies, and other people who aren't actively focused on improving society or being productive.
There are just my raw thoughts, please excuse ethics and the modern societal tendencies of political correctness and all that bullshit ...
