Can all countries share their high technology to improve our lives?

i think among countries,they are selfish more or less..but we can not change it ,,there should be some different in the world,,so our society will make progress..if not, more people will be satisfied with the technology nowadays..nomen will work hard for more wages,,do you agreee with me or not??

It should definitely be shared but sad to say profit making has become the central focal point instead of helping to aid humanity
