Of all the things that are going to come out of the next 4 years the nonstop anti-consumer mergers (and the inevitable round after round of layoffs) is going to suck the hardest. This is pretty much why progressives fought to keep the $2 trillion in cash sitting offshore outside of American. Companies have pretty much admitted that almost none of that is going into R&D and instead they plan to spend it on M&A (Mergers and Acquisitions).
You mentioned "next 4 years" as if that were a Trump thing, but you've got it backwards.
Trump appears to be completely pro-consumer in his dealings with corporations; or in other words, a "populist" leader.
Recently he came out against the anti-consumer policies of big pharma, and intends to put pressure on them to reduce consumer costs overall.
He's met with several companies and suggested that there will be a tariff on off-shored work, with the result that several companies are pledging to keep work in America.
He's also convinced Boeing to reduce costs, which isn't a consumer benefit per-se, but it saves the government from being fleeced by Boeing a little.
It really appears that he's serious about making things better for the people. He's done a small amount before being elected, and appears to be trying to keep that campaign promise.
When the article about minimum H1B salaries of $100K, people were saying "well, he got one thing right".
Give him a chance.
He might actually make things better.
