The situation the uk faces is not wholly down to Conservative incompetence. Some of our issues have been decades in the making.
The growth agenda has been stopped by the Labour left who think money grows on trees whilst at the same time taxing business even more. The basic knowledge voters need is that business generates wages, employment, and wealth. Poor business confidence and employers go elsewhere, jobs are lost and firms close. Government can only create a proportion of growth and wealth for everyone without taxes from business and non government employees. We spend far more than we earn on the state and have a culture where not earning is seen as normal. This isn’t down to the Tories alone and continually harping on about the previous governments is really trying to divert attention from the here and now and , frankly, childish.
Labour needs to face down their problem MPs (or mayors) and be firm about promoting growth. There are some great projects they are wavering on and it’s not good enough. Ditto reform of benefits and NHS. So many things have been slow burners and nothing much has happened. Reform of planning to get more houses built? It’s producing next to nothing.
As for the electorate - I’ll leave this with you. Around 5% of the electorate had sufficient economic knowledge to understand the pros and cons of Brexit. Far too many just had “feelings” and believed slogans and rhetoric. It’s probably the same for any policy area you care to look at. We are an uneducated electorate and far too many are disengaging because leaders and process is so poor.
