The prosperity of countries and how they can afford to support a decent standard of living for their citizens in a generation's time will largely come down to energy, food and water security (UK exceptionally well-placed geographically for this but squandering it) and who owns the IP for the technologies of the future in robotics, AI, medicine, new food production processes, energy generation and storage, also potentially geo-engineering.
We need to throw everything we have left (not much) at education, skills, infrastructure, tech, research on our science and tech strength areas, and design our tax and laws to protect these investments and encourage the best from around the world to come here and participate alongside homegrown talent. A full industrial strategy focused on these long-term goals for higher productivity, vociferous protection of IP like the US has, while making the UK attractive to those with the skills, brains, knowledge, experience and money to make this possible.
The irony is that a long-term industrial strategy based on the above would actually have investors keen to invest here if they were convinced it was serious and plausible, even it it meant more short-term borrowing because this is not just chucking more money down an endless drain of unreasonable publicly funded pension/ healthcare demands but actually building assets for the future (providing they are also convinced the Government wouldn't tax any such assets into oblivion).
If you care about your children and grandchildren you'd be asking politicians questions about such plans. Did any of this feature anywhere in voter's top 10 concerns at the election? Of course not. Banging on about culture wars and immigration on one side and "tax the rich" (read: anybody slightly better off than me") and other such irrelevant nonsense as usual.
What is being pursued currently bears no resemblance to the above. People will reap what they sow, just like with Brexit and those apparently confused why their standard of living has now declined. It will continue to do so while the voters are so stupid they collude with Government slogans and sim
