While you are technically correct in your definition of true democracy, the USA does have a functioning democracy in that voters can (and do) play a role in change of power (see 2008, 2016 and 2020). A true oligarchy gets power and doesn't release it. The USA has had many dramatic changes of power over the years negating your assertion of oligarchy.
While there are certainly some very rich politicians, the bigger problem is those "influencers" who use their money to get the politicians to do what they want. The problem with rich politicians if their self serving attitude in following their own "rich get richer" interests. The problem with poor politicians is that they are easy to "buy" in their quest to get richer.
I am pretty certain you won't find any "democracy" in the world with only "common worker" type politicians. Russia tried it in 1917 and look where that got them....China, Cuba, Venezuela all had so called revolutions that left them worse off.
There is no perfect system. The USA needs to find a formula to get the extremists (on both sides) out of the equation and things will settle down.
