Ok, 1 out of over 500? You did say "and some others" so lets say 5 out of over 500 or 1%. Yup, chock full of "common folk" and I would wager that ole Biden isn't as poor as that report makes him look to be.
You are arguing that members of Congress - the people who run the most powerful nation in the world - should have the average wealth of American citizens?
How many Fortune 500 CEO's and executives - companies far, far smaller than the United States government - have the average wealth of American citizens?
Their wealth shouldn't be the same, and it's not, but Congress is not a lottery people win.
Things used to be a lot worse when the Senate was known as 'the millionare's club' and was far worse about 'representing the people', who had not voted for them.
I want money to be taken out of politics, allowing people to need a lot less of it to get elected, which would help some with the 'wealth of members'.
But people often worry far too much about the wealth of the members, compared to the issue of the interests who buy them and the money THAT costs the US.
The compensation of Congress members is a drop in the ocean compared to that.
We'd have zero problem finding 535 people who would serve in Congress for zero pay - and that would be the most expensive thing to the American people we could do. They'd serve the interests.
