Obviously not.
As the head of state Nawaz Shariff and his family, particularly his wife, should get the same medical treatment from the same institutions he is chronically mismanaging and underfunding but demands the general public go to particularly in light of poor economic management that's lead to people being unable to afford better medical services because private practitioners are unable to charge higher rates in order to purchase better equipment.
When all of them just run off abroad if things get bad or don't meet their standards what incentive is there for them to actually do something good for the country and its peoples rather than themselves?
If he doesn't trust the hospitals then he needs to work to improve the hospitals otherwise f*ck off and stop rigging elections so someone else who actually cares about Pakistan and its people can make a difference.
I am very confident in Pakistani medical practitioners and one of my uncles, who happens to be a high ranking medical official, saved my life while I was in Pakistan and have a lot of family members who are doctors there.
I'd trust them with my life any day of the week so why can't Nawaz?
