all of those things have been true for decades, and in fact some of them (like crime rates) were much worse in the past. in the long term, violent crime in the us has been in decline since colonial times. the homicide rate has been estimated to be over 30 per 100,000 people in 1700, dropping to under 20 by 1800, and to under 10 by 1900.
after ww2, crime rates increased in the us, peaking from the 1970s to the early-1990s. violent crime nearly quadrupled between 1960 and its peak in 1991. property crime more than doubled over the same period. since the 1990s, however, contrary to common misconception, crime in the us has declined steadily, and has significantly declined by the late 1990s and also in the early 2000s.
after 1994, crime rates began to fall. this trend lasted until 2015, when crime rates began to rise slightly. this reversed again in 2018 and 2019, but violent crime increased significantly again in 2020. despite the increase in violent crime between 2020 and 2021, the quantity of overall crime is still far below the peak of crime seen in the us during the late 1980s and early 1990s, as other crimes such as property crime and robbery continued to decline.
the more recent decline of public education i blame a lot on the obama administration. many of their programs and objectives succeeded in catering towards the lowest common denominator (if an idiot can't figure it out, don't teach it). the only refuge is private education.
we've always had corrupt politicians, and if you think looting is bad today, you should look back to the 1960s and 1970s. the economically disadvantaged have always used riots and protests as an opportunity to pillage.
