The HRP was started as part of s theme to empower China's claims to sovereignty of certain areas with ethnic Chinese populations. It's a stupid scheme and does not take into consideration the many possible scenarios, especially in multi ethnic Hong Kong, that could arise and cause problems. I was angered when the cross border driving scheme was announced and it was only open to people with HRP…which begs the question, why is the HK government negotiating obviously discriminatory agreements with the mainland?
Anyway, there is a solution. My guess is that you engage in business and travel at least somewhat frequently in Asia. Therefore, Apply for the APEC travel pass. Its valid for three years, and the lines are shorter than for those with HRP (most of the time there is not line). You can apply online.
