The only way to get rid of them overnight is by revolution. And that has a poor track record in so many ways (which is why I prefer the tag 'democratic socialist' to 'marxist').
Good suggestions for tackling them in the medium term (over a few decades) include progressive taxation (including wealth taxes and higher inheritance tax), nationalised health services and a comprehensive social security system, universal education and legislation enshrining equal rights (including workers' rights to collective bargaining). UBI is an idea that needs more large scale trials.
Proper taxation of existing wealth, as opposed to income, is a biggie that has not been addressed properly anywhere in the West afaik. The post-war consensus was a damn thorough start on many of them, especially in Europe, but is currently in retreat under right-wing pressure.
Introduction of systems that purport to be redistributory, but actually have obvious wealthy or middle-class beneficiaries (a good example from the UK was the ridiculous 'Help-to-Buy' scheme) are a problem as well, as others have intimated, they do not undermine the principle however, merely show that it can be abused by the wealthy.
