As you mention in the piece Monopoly is a war of attrition with players turned into bystanders and only really fun for the person who's winning. I would suggest that players be forced to "declare bankruptcy" when they have no property and less than $200 in cash but remain on the board as an underclass of spoilers if you will. When they land on a property and can't pay rent they would be "freeloading" and the landlord would have to contribute a "tax credit" into the community chest in order to get them evicted. similarly if a bankrupt player lands on an ownowned property they could declare "squatters rights" and anyone who later wants to purchase that property would have to pay them to get them to release those rights. If a bankrupt person lands on community chest and collects all the fines that have been leavied they would no longer be bankrupt until their money runs out again. This would keep everyone active in the game until someone wins, (although that may never happen with these rules ;-)

I wouldn't get rid of anything but I would modify some of the chance and community chest cards to update them. Suggestions:
- Gov't Bailout cards for both the railroads and the utilities in community chest. the owner(s) of those properties collects a Gov't bailout and everyone else has to contribute $20 to the utility or railroad owner as their "tax burden" to finance it.
- Lottery winner card in chance which has a large sum going to the winner but they have to pay half that sum back in taxes to the community chest.
- Medical bankrupcy card in Chance, "Serious Medical condition is decalred a pre-existing condition by Health insurer" player has to mortgage all their property to the bank and all but $200 of their cash and declare bankruptcy becoming a bankrupt player per my new rules above.
