Law and order has been breaking down since the 60s. Too many do-gooders, no appropriate punishments,lenient sentences,releasing prisoners early because the prisons are overcrowded.
Immigration--In the years after the war we welcomed people from the Colonies on the understanding that after working here and making the money to send back to their families then after two or three years they would return home. That didn't happen because most of them stayed and raised families in the UK. Thousands more have been allowed to come here over the following years.They have had a big impact on every aspect of our society.
The economy grew fairly quickly after WW2 , wages increased, demand for material goods grew and British made goods were welcomed all over the world. Now we don't have the factories and mills any more. They have been replaced with industrial units and technology firms. Large imports from China are often shoddy but people buy them because they are cheap compared with the few goods that we make over here.
Green issues will never be solved until we get rid of plastic altogether.
NHS is struggling with the sheer volume of people with medical issues and also it is losing a lot of staff.
Education was better when we had the three tier system. Grammar, Secondary and Technical schools. Every child ,even the poorest had a reasonable chance to achieve and
live their dreams. Now all we seem to get are points systems ,overcrowded classes ,teachers leaving in their droves. No jobs at the end of their school lives leads to despair and lack of incentives.
Finally the media seems to thrive best on 'bad news'. They relish on reporting about terrorism, wars, disease and as many miserable things that they can rake up. No news is good news !
