@layman,
Soft Bank has been investing in and buying U.S. companies for several years. Odd that these Liberals didn't noitice that. Of course Soft Bank is looking for synergies with other of its investments and added market sector growth. That's what capitalism is all about, and those are precisely the appetites that makes capitalism so effective iun allocating capital to it's most productive uses.
Moreover, compared to Japan, the return on invested capital in this country is likely (under Trump, not Obama), to be much higher than Soft Bank could realize in stagnant Japan.
U.S. firms are currently sitting on hordes of capital they have been reluctant to invest in new enterprises, because they can't calculate a good outcome given the appetite of our idiot President and his Liberal advisors for new, unexpected regulations on financial rules, employee compensation, corporate liability and a host of other matters. There has been a steady flood of ths crap for the past seven years and the cumulative effect has been very chilling on business investment. That's why our economic growth is so anemic relative to our previous norms. It allso kills new job creation and drives the wage stagnation & income inequality Liberals complain about so much. Odd indeed that they don't recognize that their policies cause it.
Happily that too will soon be behind us.
