I have not lived and visited home country for several years since my family is all settled abroad so I have weak ties which I need to compensate in some other ways.Yes, someone may not show any proof at all and get his permit but it doesn't mean the same applies to all. again where one is applying from determines how severe his or her application will be scrutinized. I showed marriage cert., House documents (completed and uncompleted), land, Shares in companies, Pension account, business, insurances, offer letter from the institution I am to work upon return. So, let that be a guide.
