Stop moaning and get a part time job.
I only worked in the UK for 5 years but will get the full pension if I continue to pay £160 or so a year in voluntary class B contributions.
Great ROI unless I die.
UK state pension is a bonus, it's all about perspective.
I can build a 4 bedroom house with a pool here for under £50,000, for example. I can live in a hotel and eat breakfast, lunch and dinner in a restaurant, and a bottle of whisky daily all for £170 a week.
Better than a council flat in Aberdeen, with sideways rain, wearing a wooly bunnet, eating beans on toast.
