Link the pay of MPs and Civil Servants to people's average disposable income

Background

Total remuneration (pay, bonuses, expenses, etc.) should be linked to median disposable incomes of the population (after taxes, housing costs, energy bills, etc.). If disposable incomes rise, MP and civil servants are rewarded; if they drop, then MPs and civil service remuneration is cut by double.

Additional details

For at least three decades, governments have made decisions that have made UK citizens poorer. House prices, insane rents, energy prices, expensive food, high taxes, rampant immigration, and more are governments decisions that make us poorer. In order to ensure that our politicians are genuinely working for the benefit of the people of the UK, we need to align incentives: if politico decisions make people poorer, then they should be made poorer too. Align politico pay incentives to our benefit.
