Manufacturing remains the second most common route to billionaire status. Reinhold Wuerth, a German entrepreneur, tops the list with a net worth of $29.7 billion. Wuerth’s success stems from his family’s screw and fastener business, which he transformed into a $16 billion giant since assuming control in 1954. Among the notable newcomers are Richard and Elizabeth Uihlein, each worth $3.8 billion, who established Uline, a packaging distributor. Also noteworthy is Michal Strnad, a 30-year-old Czech Republic citizen with a net worth of $2 billion, who inherited the leading arms and ammunition supplier Czechoslovak Group from his father in 2018.
