DSL (when not of the ATT U-verse variety) barely gets over 10-Mbit in practice, with speeds closer to 3-Mbit being fairly common.
Satellite can't really be considered high-speed due to latency.
LTE coverage is still poor, and I've yet to see hardware suitable for a home connection for it. (Tethering via a cellphone doesn't count.)
So, no. There's really generally one, maybe two choices for home high-speed internet so it's not like customers can vote with their dollars and move to a Netflix-friendly ISP.
Well, they don't get free access to the lines, they still pay rates, typically, from what I understand around 15-35% lower than the usual consumer prices per customer to the "main" provider on that line. If that's really not enough for them to continue maintaining and improving their infrastructure perhaps it would be an issue - but it certainly appears to have been sufficient here at least.
Satellite has caps and active throttling which prevent video streaming, so no Netflix for you.
On DSL, if your sync rate is 3Mbps, you won't be watching anything in HD and unless you dedicate the line for only Netflix and ban everybody else in the house from using the internet, you'll get poor quality SD only.
So, no, DSL and satellite are not plenty fast enough for Netflix.
