The big problem here is the Tories 13 years of economic stewardship has been a total disaster. Many of us were shielded enough not to feel it acutely, but those with the least have been feeling it for a decade or more.
At its core, the Tories have not done enough to spur sound economic growth.
Under the last Labour Government, from 1997 to 2010, the economy grew by 60% (and that's after you account for the financial crash in 2008-09). About 4.6% a year. Under the Tories from 2010 to 2021, it grew by just 25% or 2.3% a year.
But it gets much worse. In real terms - i.e. after accounting for inflation - the economy grew by 33% under Labour (2.5% a year) but under the Tories, the real growth has been 0.7% in 11 years - that's 0.06% a year.
Why is that relevant to what sort of wages can be afforded? Well, if the economy had grown under the Tories at the same rate as under Labour, UK GDP in 2023 would be worth about $1 trillion more than it actually is.
What does that mean? It means (with the right policies at least) more money for higher wages in the private sector, more tax revenue, less dependence on benefits, particularly in work benefits like tax credits.
There is a difficult fiscal position now - but it is entirely of the Tories making because the economy has essentially flatlined for the last thirteen years.
