It's accumulated wealth that is the problem (and leads to the corruption of free markets and democracy).
Policies should be focused on that - taxing wealth rather than work, and encouraging profitable investments rather than sitting on assets.
Whereas now the so-called "left-wing" policies are awful - rent control is popular in Europe despite being an unfair disaster in Sweden. There are high taxes on income and high VAT, whilst inheritance, land and wealth taxes have been abolished, greatly hurting social mobility while benefiting established, inherited wealth.
Same with a lot of focus on patching up symptoms - like not prosecuting low-value shoplifting, allowing squatting on "empty" properties, etc. rather than trying to improve market conditions, education and training and the housing market, etc. to ensure that everyone could get a much better salary to begin with.
