     酒(しゅ)税(ぜい)は、これらの者(もの)の負(ふ)担(たん)となり、特(とっ)級(きゅう)ウイスキーや特(とっ)級(きゅう)清(せい)酒(しゅ)は、社(しゃ)用(よう)族(ぞく)が飲(の)むからその高(たか)い酒(しゅ)税(ぜい)は、主(しゅ)として企(き)業(ぎょう)家(か)あるいは株(かぶ)主(ぬし)の負(ふ)債(さい)となる

     As for the liquor tax, since top shelf whisky or high-quality sake is drunk by shayōzoku the burden of those high taxes falls mainly on the owners or the shareholders
