There is a problem with the definition of the '1%'.
Politicians typically want the masses to believe that the so-called '1%' are people owning super yachts, dozens of luxury mansions around the globe and private jets. In reality the income level to become part of the 1% is about USD 380.000 annual income in the United States or EUR 180.000 in Germany. Well-off, but hardly really 'rich'. The people with the private jets are actually more like the 0,001%.
Of course, those '0,001%' often simply don't care about the level of income taxes at all, because the have ways and means to avoid them. So, raising taxes for the '1%' actually doesn't target the super rich; it targets people which are more like upper-upper middle class: Doctors, lawyers, architects, small and medium size business owners.
It's all propaganda bullshit.
