One always has to be careful of suggesting things are getting worse, as it risks implying there was some earlier golden age, however I do think members of Congress get away with an incredible amount of corruption (whether legal or not) that would've violated NORMS twenty years ago.
Generally I think "not technically illegal (maybe)" has justified things which were once just understand to be scummy whether or not you could get the prosecutors (themselves, also, too, often corrupt) involved.
