But these sorts of problems have always existed pandemic or no pandemic.
Those in high rise flats are never going to face flooding! If they don't like it move! And why procreate if the accommodation is unsuitable!?
Those with violent and/or abusive partners need to find it in themselves to break free and end the relationship.
No teenager is going to come to any harm because he/she can't hook up with his/her girlfriend/boyfriend for a few weeks or even longer.
Of course the sick and elderly need taking care of.
Yes, social problems have always existed, but they must be accentuated if one has to remain in the same home as a partner who is causing them harm. Normally, one can "escape" for a while, or stay somewhere else, or even go to work!
Teenagers can be very emotional. I would guess that being parted from someone they love (or think they love) might even lead to suicide attempts, or actual suicide in a vulnerable individual.
Many people don't choose to live in high rise flats: it is all they can afford. As for leaving an abusive relationship, people don't for a number of reasons: they can't afford to, or, despite everything, they need the "status" of having a partner, or they have children and wont leave them.
There will be a number of people who have lost their jobs and cant make ends meet. They no longer love their partners. Their kids are getting on their nerves. Throw alcohol into the mix, and all kinds of awful things can happen.
