Your rudimentary knowledge about Pakistan and the lack of knowledge about Pakistan society has to be blamed.
A few Pakistanis going to India doesn't mean millions of people who goes to Pakistani hospitals has't got the facilities. Many NRP's from US visits Pakistani hospitals for medical and dental treatment, that doesn't mean US hasn't got the facilities.
Pakistan has good hospitals, good universities(7 universities in QS top 300 ranking in Asia), MNC industry including FMCG is big in Pakistan, like Nestle and Unilever per capita sales of consumer goods in Pakistan is twice that of India...Google search about it. Many big Pakistani consumer goods company as well like Engro, National foods, EBM, many dozen more...self sufficient in all the consumer and food stuff.
