What makes you think that current taxation is wisely spend and that in order to have a minimum income it'd be necessary to raise taxes? Just by curtailing the tax avoidance that's taking place on the top companies you got your problem solved. I mean it's kinda sad to see people that are apparently ok with the idea of funding nukes through their tax money but are quite resistant towards any  social program.

Regarding the "as long as s/he get's a job" attitude. Who holds the bargaining position when it comes to a job? Why should the grandchild of a landowner who got his property by a mad king be in the favour of the state (guarantee of property)?
