I've known people who had chronic fatigue syndrome. The symptoms are pretty much identical to what is now called "Long Covid". It is real. They just don't understand what causes it. As I said, I suspect tht in time they will find a different corona virus will likely turn out to be the cause, the only difference is that the virus that will turn out to cause chronic fatigue syndrome, just didn't cause a lot of deaths. Remember the common cold is a type of corona virus. So, an unknown corona virus that causes cold like symptoms could in some cases have the long term effect of Chronic Fatigue Syndrome.

We live in an imperfect world where the individual has very little protection from the wilful depradations of governments & corporations employing lawyers to circumvent what few inadequate rules prevent them from obtaining free handouts or as happens in many cases simply stealing from the individual because of their superior ability to do so.
Therefore if some individual has managed to gain what you call a free handout good luck to them. In reality they have gained little as what you perceive to be largesse usually results in the recipient having to live in a standard usually only ¼ or less that of everyone else who is now provided with an easy target of condemnation & inferiority.
Have you ever considered that it may be your selfish stupidity & deliberate indoctrination by governments & corporations that has resulted in your attitude to those you call out to be lazy? I have seen many employed people who do not work for most of their shift but hold their hand out at the end of it to be paid
