If I say you can forget the $10k for your vote and accept that you either vote for my preferred candidate or you're fired/beaten, suddenly the secret ballot starts looking like a good idea again.

And that's even before we conclude the preferred candidate of the plutocratic oligraphy would actually be massively aided by being able efficiently purchase the votes of the indifferent rather than having to inefficiently purchase airtime to convince people their candidate actually has merit. (And of course they'll still be able to continue to organise their vote-buying operations through shadowy umbrella organizations to the extent they can be bothered to disguise who they want to win)
